KUALA LUMPUR - Intelligence checks on the 153 Chinese passengers aboard a missing Malaysian airliner produced no red flags, China said Tuesday, as investigators struggled to clarify events that led to the plane's dramatic disappearance.
Eleven days after contact was lost with Flight 370 and its 239 passengers and crew, there has been minimal progress in determining what transpired when the Boeing 777 was deliberately diverted off its flight path and where it might have gone.
Two thirds of those on board were Chinese, and Malaysia had asked the authorities in Beijing to run an exhaustive background check on all their nationals.
Particular attention had been paid to one passenger from China's Muslim ethnic Uighur minority, separatist elements of which have become increasingly militant in their struggle against Chinese rule.
On Tuesday, China's ambassador to Malaysia Huang Huikang said no evidence had been found that would link anyone to a possible hijacking or terrorist attack on the jet, the official Xinhua news agency reported.
Huang also said China had begun searching for the aircraft in its own territory but gave no further details.
