Police offer confused testimony in Pistorius case

PRETORIA, South Africa (AP) — The detective leading the police investigation into Oscar Pistorius' fatal shooting of his girlfriend offered confusing testimony Wednesday, at one point agreeing with the athlete's defense that officers had no evidence challenging the runner's claim he accidentally killed her.

Testimony by Detective Warrant Officer Hilton Botha of the South African Police Service left prosecutors rubbing their temples, only able to look down at their notes as he misjudged distances and acknowledged a forensics team left in the toilet bowl one of the bullet slugs fired at Reeva Steenkamp. However, Botha still poked holes in Pistorius' own account that he feared for his life and opened fire on Valentine's Day after mistaking Steenkamp for an intruder.

The second day of the bail hearing in a case that has riveted South Africa and much of the world appeared at first to go against the double-amputee runner, with prosecutors saying a witness can testify to hearing "non-stop talking, like shouting" between 2 a.m. and 3 a.m. before the predawn shooting on Feb. 14. However, Botha later said under cross examination that the person who overheard the argument was in a house 600 meters (yards) away in Pistorius' gated community in the suburbs of South Africa's capital, Pretoria.

Later, prosecutor Gerrie Nel questioned Botha again and the detective acknowledged the distance was much closer. But confusion reigned for much of his testimony, when at one point Botha said officers found syringes and steroids in Pistorius' bedroom. Nel quickly cut the officer off and said the drugs were actually testosterone.

Pistorius' lead defense lawyer, Barry Roux, asserted when questioning the detective — who has 16 years' experience as a detective and 24 years with the police — that it was not a banned substance and that police were trying to give the discovery a "negative connotation."

"It is an herbal remedy," Roux said. "It is not a steroid and it is not a banned substance."

The name of the drug, offered later in court by Roux, could not be immediately found in reference materials by The Associated Press. A spokesman for prosecutors later said it's too early to know what the substance is, as they don't yet have results of forensic testing on the material.

Pistorius, 26, said in an affidavit read in court Tuesday that he and his 29-year-old girlfriend had gone to bed and that when he awoke during the night he detected what he thought was an intruder in the bathroom. He testified that he grabbed his 9 mm pistol and fired into the door of a toilet enclosed in the bathroom, only to discover later to his horror that Steenkamp was there, mortally wounded.

Pistorius, the first Paralympian runner to compete at the Olympics, is charged with premeditated murder in the case.

The prosecution attempted to cement its argument that the couple had a shouting match, that Steenkamp fled and locked herself into the toilet stall of the bathroom and that Pistorius fired four shots through the door, hitting her with three bullets.

Botha said: "I believe that he knew that Reeva was in the bathroom and he shot four shots through the door."

But asked if the police found anything inconsistent with the version of events presented by Pistorius, Botha responded that they had not. He later said nothing contradicted the police's version either.

Nel projected a plan of the bedroom and bathroom in the courtroom and argued that Pistorius had to walk past his bed to get to the bathroom and could not have done so without realizing that Steenkamp was not in the bed.

"There's no other way of getting there," Nel said.

Botha said the trajectory of the bullets showed the gun was fired pointed down and from a height. This seems to conflict with Pistorius' statement Tuesday, because the athlete said that he did not have on his prosthetics and on his stumps and feeling vulnerable because he was in a low position when he opened fired.

Officers also found .38-caliber pistol rounds in a safe, which Botha said Pistorius owned illegally and for which he said the athlete would be charged with a crime. However, Botha also acknowledged investigators didn't take photographs of the ammunition and let Pistorius' supporters at the crime scene take them away.

Botha said the holster for the 9 mm pistol was found under the left side of the bed, the side on which Steenkamp slept. He also implied it would have been impossible for Pistorius to get the gun without checking to see if Steenkamp was there. Roux later argued that Pistorius had suffered an injury to his right shoulder and wore a "medical patch" the night of the killing which forced him to sleep on the left side of the bed.

Steenkamp was shot in the head over her right ear and in her right elbow and hip, breaking her arm and hip, Botha said. However, Roux later asked Botha if Steenkamp's body showed "any pattern of defensive wounds." The detective said no.

Botha also said the shots were fired from 1.5 meters (five feet), and that police found three spent cartridges in the bathroom and one in the hallway connecting the bathroom to the bedroom. However, later on cross-examination by the defense, Botha said he wasn't a forensics expert and couldn't answer some questions.

Police also found two iPhones in the bathroom and two BlackBerrys in the bedroom, Botha said, adding that none had been used to phone for help. Roux later suggested that a fifth phone, not collected by the police, was used by Pistorius to make calls for a hospital and help. After the hearing, Roux told journalists that Pistorius' defense team had the phone, but did not elaborate.

Guards at the gated community where Pistorius lives did call the athlete, Botha said. The detective said that all the athlete said was: "I'm all right."

He didn't hang up, Botha said, and the guards heard him uncontrollably weep.

"Was it part of his premeditated plan, not to switch off the phone and cry?" Roux asked sarcastically.

Trade unions' strike: Stick backfires, Mamata Banerjee offers carrot to traders

KOLKATA: Chastened by the widespread outrage among traders—who kept their shutters down despite her brandishing a stick, making Day One of the strike called by central trade unions a partial success—chief minister Mamata Banerjee decided to hand out carrots to the few who answered her call and kept their shops open on Wednesday.

Sources said Mamata asked mayor Sovon Chatterjee to work out an incentive to reward shop-owners who stayed open so that it encourages others to follow suit the next time. The decision was taken on the spur of the moment during an inspection of the city the CM undertook with the mayor in the early afternoon.

Mamata was initially taken aback at the sight of downed shutters in the wholesale belt of Burrabazar and Posta, but was relieved to see the vegetable market in Sealdah open.

Sources said the incentive idea struck her when she realized that cancelling the trade licences of those who stayed shut is not an option: the state will have to punish about 85% shopkeepers in the city then.

"I thank everyone who has opened their shop," Mamata said. "More shops are expected to open in the next half of the day. As for those that stayed shut, the high court has issued an order and the law will take its course."

Chatterjee said: "We are making a list of shops that were open. We will reward them." But officials in the Kolkata Municipal Corporation's licence department said there is no such rule and implementing the reward scheme will be difficult.

Mamata's decision to discuss the matter only with Forum of Traders' Organization (West Bengal) general secretary Rabindranath Koley boomeranged as other federations were aggrieved and did all they could to foil the government's efforts to keep shops open.

"Traders have shown politicians that they will not be scared into submission," said Tarak Trivedi of the Federation of Trade Organization that claims 50 lakh businessmen as members. "Treat us with respect and we will extend a helping hand."

On Tuesday, it was Koley who had announced the decision to take "uncooperative" traders to task. On Wednesday, he did the task of mollifying.

He said the CM is trying out various measures to lure traders away from the culture of staying at home during strikes. "In Kankurgachi, VIP, New Market, Gariahat, Lake Market and elsewhere, 50% shops were open," Koley said. "That is a long way from the scenes in the past when everything would be shut. The trading community is timid and needs to be encouraged to defy political strikes."

Timidity was, however, not the trait traders displayed when they defied the CM's threat of licence cancellation. "Had she called all the trade organizations and appealed to us to stay open, an overwhelming majority of shop-owners would have complied," said Atmaram Kajaria, president of the Federation of West Bengal Trade Association that claims to represent two crore traders in the state. "But by issuing a threat that is impractical and impossible to carry out, the CM suffered a loss of face that she could have easily avoided."

Though all trade unions, barring Citu, have decided to continue with the strike on Thursday, trade bodies said the scene will be different in Kolkata and most shops will open for business.

Scientists use 3-D printing to help grow an ear

WASHINGTON (AP) — Printing out body parts? Cornell University researchers showed it's possible by creating a replacement ear using a 3-D printer and injections of living cells.

The work reported Wednesday is a first step toward one day growing customized new ears for children born with malformed ones, or people who lose one to accident or disease.

It's part of the hot field of tissue regeneration, trying to regrow all kinds of body parts. Scientists hope using 3-D printing technology might offer a speedier method with more lifelike results.

If it pans out, "this enables us to rapidly customize implants for whoever needs them," said Cornell biomedical engineer Lawrence Bonassar, who co-authored the research published online in the journal PLoS One.

This first-step work crafted a human-shaped ear that grew with cartilage from a cow, easier to obtain than human cartilage, especially the uniquely flexible kind that makes up ears. Study co-author Dr. Jason Spector of Weill Cornell Medical Center is working on the next step — how to cultivate enough of a child's remaining ear cartilage in the lab to grow an entirely new ear that could be implanted in the right spot.

Wednesday's report is "a nice advancement," said Dr. Anthony Atala, director of the Institute for Regenerative Medicine at Wake Forest Baptist Medical Center, who wasn't involved in the new research.

Three-dimensional printers, which gradually layer materials to form shapes, are widely used in manufacturing. For medicine, Atala said the ear work is part of broader research that shows "the technology now is at the point where we can in fact print these 3-dimensional structures and they do become functional over time."

Today, people who need a new ear often turn to prosthetics that require a rod to fasten to the head. For children, doctors sometimes fashion a new ear from the stiffer cartilage surrounding ribs, but it's a big operation. Spector said the end result seldom looks completely natural. Hence the quest to use a patient's own cells to grow a replacement ear.

The Cornell team started with a 3-D camera that rapidly rotates around a child's head for a picture of the existing ear to match. It beams the ear's geometry into a computer, without the mess of a traditional mold or the radiation if CT scans were used to measure ear anatomy.

"Kids aren't afraid of it," said Bonassar, who used his then-5-year-old twin daughters' healthy ears as models.

From that image, the 3-D printer produced a soft mold of the ear. Bonassar injected it with a special collagen gel that's full of cow cells that produce cartilage — forming a scaffolding. Over the next few weeks, cartilage grew to replace the collagen. At three months, it appeared to be a flexible and workable outer ear, the study concluded.

Now Bonassar's team can do the process even faster by using the living cells in that collagen gel as the printer's "ink." The 3-D technology directly layers the gel into just the right ear shape for cartilage to cover, without having to make a mold first.

The next step is to use a patient's own cells in the 3-D printing process. Spector, a reconstructive surgeon, is focusing on children born without a fully developed external ear, a condition called microtia. They have some ear cartilage-producing cells in that tissue, just not enough. So he's experimenting with ways to boost those cells in the lab, "so we can grow enough of them from that patient to make an ear," he explained.

That hurdle aside, cartilage may be the tissue most amenable to growing with the help of 3-D printing technology, he said. That's because cartilage doesn't need blood vessels growing inside it to survive.

Armstrong Snubs Offer From Anti-Doping Officials

Lance Armstrong has turned down what may be his last chance at reducing his lifetime sporting ban.

Armstrong has already admitted in an interview with Oprah Winfrey to a career fueled by doping and deceit. But to get a break from the U.S. Anti-Doping Agency, all he had to do was tell his story to those who police sports doping. The deadline was today, and Armstrong now says he won't do it.

"For several reasons, Lance will not participate in USADA's efforts to selectively conduct American prosecutions that only demonize selected individuals while failing to address the 95 percent of the sport over which USADA has no jurisdiction," said Tim Herman, Armstrong's longtime lawyer. "Lance is willing to cooperate fully and has been very clear: He will be the first man through the door, and once inside will answer every question, at an international tribunal formed to comprehensively address pro cycling."

But the "international tribunal" Armstrong is anxious to cooperate with has one major problem: It doesn't exist.

The UCI, cycling's governing body, has talked about forming a "truth and reconciliation" commission, but the World Anti-Doping Agency has resisted, citing serious concerns about the UCI and its leadership.

WATCH: Armstrong's Many Denials Caught on Tape

U.S. Anti-Doping Agency officials seemed stunned by Armstrong's decision simply to walk away.

"Over the last few weeks, he [Armstrong] has led us to believe that he wanted to come in and assist USADA, but was worried of potential criminal and civil liability if he did so," said Travis Tygart, CEO of the U.S. Anti-Doping Agency. "Today, we learned from the media that Mr. Armstrong is choosing not to come in and be truthful and that he will not take the opportunity to work toward righting his wrongs in sport."

Armstrong's ongoing saga plays out amid a backdrop of serious legal problems.

Sources believe one reason Armstrong wants to testify to an international tribunal, rather than USADA, is because perjury charges don't apply if Armstrong lies to a foreign agency, they told ABC News.

While Armstrong has admitted doping, he has not given up any details, including the people and methods required to pull off one of the greatest scandals in all of sport.

Armstrong is facing several multimillion-dollar lawsuits right now, but his biggest problems may be on the horizon. As ABC News first reported, a high-level source said a criminal investigation is ongoing. And the Department of Justice also reportedly is considering joining a whistleblower lawsuit claiming the U.S. Postal Service was defrauded out of millions of dollars paid to sponsor Armstrong's cycling team.

Gbagbo lawyer slams "political trial" at ICC

THE HAGUE: Laurent Gbagbo's lawyer hit out at a "political trial" at the International Criminal Court on Wednesday, where judges are to decide if the Ivorian ex-president should face charges of crimes against humanity.

Gbagbo, 67, is the first former head of state brought before the ICC, where he is accused of masterminding a campaign of violence during a bloody 2010-2011 presidential election standoff in the West African nation in which over 3,000 people died.

"The Ivorian people deserve better than a political trial, they deserve a trial of those who are really responsible for the country's decade-long destruction and the court deserves to have been able to look at what really happened in Ivory Coast," lawyer Emmanuel Altit told the court on the second day of the confirmation of charges hearing.

Gbagbo maintains that he is the rightful president of Ivory Coast and that he was evicted in favour of his rival, current President Alassane Ouattara, thanks to a plot led by former colonial ruler France.

Gbagbo faces four counts of crimes against humanity for allegedly fomenting the wave of violence. He has denied the charges against him.

Altit said the evidence against Gbagbo had holes in it and did not represent reality.

"Why aren't they here, why aren't they being prosecuted?" said Altit, listing officials in Ouattara's government.

While thousands died during the five-month standoff, forces loyal to Gbagbo as well as those loyal to Ouattara have been accused of massive human rights abuses.

Prosecutors and the defence are to spend just over a week arguing their cases before a three-judge bench, who will then decide if there are "substantial grounds to believe that Gbagbo committed the crimes" and should be charged.

The prosecution says Gbagbo masterminded a plan to "stay in power by all means... through carefully planned, sustained and deadly attacks" against Ouattara supporters.

Between November 28, 2010 and May 8, 2011 Gbagbo's forces killed between 706 and 1,059 people and raped more than 35 women, prosecutors say.

His supporters have accused Ouattara's camp of practising "victor's justice" as many of the former president's backers are now behind bars -- including Gbagbo's wife Simone, who is also wanted by the ICC -- while none of those close to the Ouattara regime have been arrested.

The hearings started on Tuesday and are to last over a week, with Gbagbo expected to speak on the final day, February 28.

Syria "Scud-type" missile said to kill 20 in Aleppo

AMMAN (Reuters) - A Syrian missile killed at least 20 people in a rebel-held district of Aleppo on Tuesday, opposition activists said, as the army turns to longer-range weapons after losing bases in the country's second-largest city.

The use of what opposition activists said was a large missile of the same type as Russian-made Scuds against an Aleppo residential district came after rebels overran army bases over the past two months from which troops had fired artillery.

As the uprising against President Bashar al-Assad, now a civil war, nears its two-year mark, rebels also landed three mortar bombs in the rarely-used presidential palace compound in the capital Damascus, opposition activists said on Tuesday.

The United Nations estimates 70,000 people have been killed in the conflict between largely Sunni Muslim rebels and Assad's supporters among his minority Alawite sect. An international diplomatic deadlock has prevented intervention, as the war worsens sectarian tensions throughout the Middle East.

A Russian official said on Tuesday that Moscow, which is a long-time ally of Damascus, would not immediately back U.N. investigators' calls for some Syrian leaders to face the International Criminal Court for war crimes.

Moscow has blocked three U.N. Security Council resolutions that would have increased pressure on Assad.

Casualties are not only being caused directly by fighting, but also by disruption to infrastructure and Syria's economy.

An estimated 2,500 people in a rebel-held area of northeastern Deir al-Zor province have been infected with typhoid, which causes diarrhea and can be fatal, due to drinking contaminated water from the Euphrates River, the World Health Organization (WHO) said on Tuesday.

"There is not enough fuel or electricity to run the pumps so people drink water from the Euphrates which is contaminated, probably with sewage," the WHO representative in Syria, Elisabeth Hoff, told Reuters by telephone.

The WHO had no confirmed reports of deaths so far.

BURIED UNDER RUBBLE

In northern Aleppo, opposition activists said 25 people were missing under rubble of three buildings hit by a several-meter-long missile. They said remains of the weapon showed it to be a Scud-type missile of the type government forces increasingly use in Aleppo and in Deir a-Zor.

NATO said in December Assad's forces fired Scud-type missiles. It did not specify where they landed but said their deployment was an act of desperation.

Bodies were being gradually dug up, Mohammad Nour, an activist, said by phone from Aleppo.

"Some, including children, have died in hospitals," he said.

Video footage showed dozens of people scouring for victims and inspecting damage. A body was pulled from under collapsed concrete. At a nearby hospital, a baby said to have been dug out from wreckage was shown dying in the hands of doctors.

Reuters could not independently verify the reports.

Opposition activists also reported fighting near the town of Nabak on the Damascus-Homs highway, another route vital for supplying forces in the capital loyal to Assad, whose family has ruled Syria since the 1960s.

Rebels moved anti-aircraft guns into the eastern Damascus district of Jobar, adjacent to the city centre, as they seek to secure recent gains, an activist said.

"The rebels moved truck-mounted anti-aircraft guns to Jobar and are now firing at warplanes rocketing the district," said Damascus activist Moaz al-Shami.

Russian Deputy Foreign Minister Gennady Gatilov told a news conference a U.N. war crimes report, which accuses military leaders and rebels of terrorizing civilians, was "not the path we should follow ... at this stage it would be untimely and unconstructive."

Syria is not party to the Rome Statute that established the ICC and the only way the court can investigate the situation is if it receives a referral from the Security Council, where Moscow is a permanent member.

Sukhoi crashes in Rajasthan, pilots eject safely

NEW DELHI: A frontline Sukhoi-30MKI fighter crashed at the Pokhran range in Rajasthan on Tuesday evening. The two experienced pilots, Squadron Leaders G B S Chauhan and A R Tanta, managed to eject safely.

While the court of inquiry will establish the exact reason behind the crash, preliminary reports blamed a "technical snag" for the mishap. The aircraft was undertaking night-flying drills as part of rehearsals for the massive IAF fire power display at the Pokhran range slated for February 22 when the technical problem took place around 7.20 pm.

The over 160 Sukhois inducted by IAF till now — 272 of them have been contracted from Russia in deals worth Rs 55,717 crore - were "temporarily grounded" at Pune, Bareilly, Tezpur, Chabua and other airbases after one had crashed in December 2011. The probe then had blamed the failure of the fly-by-wire (FBW) system for the crash.

IAF chief Air Chief Marshal N A K Browne had himself taken to the skies in a Sukhoi within a week to show "all was well" with India's latest and most potent fighters, which are progressively being based on both the western and eastern fronts against Pakistan and China.

The Sukhois, with just four crashes in around 90,000 hours of flying over the last 13 years, have had a good track-record with IAF. But with the bulk of the 272 Sukhois ordered being manufactured by HAL under transfer of technology from Russia, a hard-nosed look at quality, maintenance and servicing issues at the defence PSU is certainly needed.

Costlier robotic surgery soars for hysterectomies

CHICAGO (AP) — Robotic surgery is increasingly being used for women's hysterectomies, adding at least $2,000 to the cost without offering much benefit over less high-tech methods, a study found.

The technique was used in just 0.5 percent of operations studied in 2007, but that soared to almost 10 percent by early 2010. Columbia University researchers analyzed data on more than 260,000 women who had their wombs removed at 441 U.S. hospitals for reasons other than cancer. The database covered surgeries performed through the first few months of 2010.

Women who had the robotic operations were slightly less likely to spend more than two days in the hospital, but hospital stays were shorter than that for most women. Also, complications were equally rare among robotic surgery patients and those who had more conventional surgeries. Average costs for robotic hysterectomies totaled nearly $9,000, versus about $3,000 for the least expensive method, a different type of minimally invasive technique using more conventional surgery methods.

Traditionally hysterectomies were done by removing the womb through a large abdominal incision. Newer methods include removing the uterus through the vagina and minimally invasive "keyhole" abdominal operations using more conventional surgery methods, or surgeon-controlled robotic devices.

Robotic operations involve computer-controlled long, thin robot-like "arms" equipped with tiny surgery instruments. Surgeons operate the computer and can see inside the body on the computer screen, through a tiny camera attached to the robotic arms. The initial idea was for surgeons to do these operations miles away from the operating room, but robotic operations now are mostly done with the surgeon in the same room as the patient.

Theoretically, robotic surgeries make it easier to maneuver inside the patient, and are increasingly used for many types of operations, not just hysterectomies.

The main explanation for the big increase "is that robotic surgery has been marketed extensively to not only hospitals and physicians, but also directly to patients. There is minimal data in gynecology that it is advantageous," said Dr. Jason Wright, an assistant professor of women's health and the study's lead author.

The study was published Tuesday in the Journal of the American Medical Association.

"Our findings highlight the importance of developing rational strategies to implement new surgical technologies," the researchers wrote.

They note that 1 in 9 U.S. women will undergo a hysterectomy, usually after the age of 40. Reasons include fibroids and other non-cancerous growths, abnormal bleeding, and cancer.

Traditional abdominal operations remain common and more than 40 percent of women studied had them, costing on average about $6,600.

A JAMA editorial says the study doesn't answer whether the robotic method might be better for certain women, and says more research comparing methods is needed. Still, it says doctors and hospitals have a duty to inform patients about costs of different surgery options.

Dr. Myriam Curet of manufacturer Intuitive Surgical of Sunnyvale, Calif., said surgical robots can help surgeons overcome the limitations of other minimally invasive methods for very overweight patients, those with scarring from other surgeries and other complexities.

Report Fingers Chinese Military Unit in US Hacks

A Virginia-based cyber security firm has released a new report alleging a specific Chinese military unit is likely behind one of the largest cyber espionage and attack campaigns aimed at American infrastructure and corporations.

In the report, released today by Mandiant, China's Unit 61398 is blamed for stealing "hundreds of terabytes of data from at least 141 organizations" since 2006, including 115 targets in the U.S. Twenty different industrial sectors were targeted in the attacks, Mandiant said, from energy and aerospace to transportation and financial institutions.

Mandiant believes it has tracked Unit 61398 to a 12-story office building in Shanghai that could employ hundreds of workers.

"Once [Unit 61398] has established access [to a target network], they periodically revisit the victim's network over several months or years and steal broad categories of intellectual property, including technology blueprints, proprietary manufacturing processes, test results, business plans, pricing documents, partnership agreements, and emails and contact lists from victim organizations' leadership," the report says.

The New York Times, which first reported on the Mandiant paper Monday, said digital forensic evidence presented by Mandiant pointing to the 12-story Shangai building as the likely source of the attacks has been confirmed by American intelligence officials. Mandiant was the firm that The Times said helped them investigate and eventually repel cyber attacks on their own systems in China last month.

The Chinese government has repeatedly denied involvement in cyber intrusions and Chinese Foreign Ministry spokesperson Hong Lei said today that the claims in the Mandiant report were unsupported, according to a report by The Associated Press.

"To make groundless accusations based on some rough material is neither responsible nor professional," he reportedly said.

Mandiant's report was released a week after President Obama said in his State of the Union address that America must "face the rapidly growing threat from cyber attack."

"We know hackers steal people's identities and infiltrate private e-mail. We know foreign countries and companies swipe our corporate secrets. Now our enemies are also seeking the ability to sabotage our power grid, our financial institutions, and our air traffic control systems. We cannot look back years from now and wonder why we did nothing in the face of real threats to our security and our economy," he said.

Though Obama did not reference China or any country specifically, U.S. officials have previously accused the Asian nation of undertaking a widespread cyber espionage campaign.

Referring to alleged Chinese hacking in October 2011, House Intelligence Committee Chairman Rep. Mike Rogers (R-Mich.) said in an open committee meeting that he did not believe "that there is a precedent in history for such a massive and sustained intelligence effort by a government agency to blatantly steal commercial data and intellectual property."

Rogers said that cyber intrusions into American and other Western corporations by hackers working on behalf of Beijing -- allegedly including attacks on corporate giants like Google and Lockheed Martin -- amounted to "brazen and widespread theft."

"The Chinese have proven very, very good at hacking their way into very large American companies that spend a lot of money trying to protect themselves," cyber security expert and ABC News consultant Richard Clarke said in an interview last week.

Yemen military aircraft crashes in Sanaa, kills 12

SANAA: A Yemeni military aircraft ploughed into a building in a residential neighbourhood of Sanaa on Tuesday, killing the pilot and at least 11 civilians, medics and witnesses said.

Medics said the toll, which included two children and three women and left another 22 injured, was expected to rise

Several hours after the crash rescue teams were still sifting through the rubble in search of any survivors in the Qadissiya area of homes and shops near Change Square, epicentre of the 2011 uprising that ousted president Ali Abdullah Saleh.

A military source identified the plane as a Russian-made Sukhoi SU-22 attack aircraft, but was unable to say what caused the crash that he said killed pilot Mohammed Shaker.

The defence ministry said the pilot was returning to his base after a training mission and had asked authorisation to land when suddenly the aircraft lost altitude and crashed. An investigation is underway.

"I saw the plane drop and we were afraid it would crash on Sanaa University, but the pilot crashed on nearby buildings," said Mohammed al-Sabri.

The aircraft hit one building on Rabat Avenue in eastern Sanaa, then smashed into another before finally crashing on top of a third, witnesses said.

An AFP correspondent said the building was badly damaged and that several ambulances rushed to the scene as helicopters hovered overhead.

A loud explosion shook the area when the crash occurred, witnesses said. Thick black smoke billowed over the district, where several cars were ablaze.

Panicked residents took to the streets, many screaming.

"We heard a loud explosion and we thought it was a mortar shell that landed on the neighbourhood," one of the residents, Taha al-Inad, told AFP.

An air base is located near the Sanaa international airport, just 15 kilometres (nine miles) north of the capital.

Tuesday's crash was the latest in a series of air accidents in the impoverished Arabian Peninsula country.

In November, a Yemeni air force Antonov M26 crashed during a training mission in a northern district of Sanaa, killing all 10 on board.

A fighter jet crashed on takeoff on a routine training mission in the south in October, killing the pilot and injuring another crew member, after what the defence ministry described as a "technical failure."

And in October 2011, four people were killed when an Antonov crashed on landing at Al-Anad air base in southern Yemen.

Sanaa was gripped by violent clashes between rival military groups during the 2011 uprising to oust Saleh, who finally stepped down a year ago under a UN-backed power transition agreement brokered by the Gulf Cooperation Council.
