Malaysian Airlines says there is still no information on the location of its flight MH 370, more than 24 hours after it lost contact with ground.
The airline spokesman said early Sunday that rescue teams have "failed to find evidence of any wreckage."
The flight, a Boeing 777-200, lost contact with ground control at 1:20 a.m. Beijing time on Saturday when it was flying over the Ho Chi Minh air traffic control area in Vietnam.
On board were 227 passengers from 14 countries, including 154 Chinese, and 12 Malaysian flight crew.
A team of 93 staff from the airline arrived in Beijing late Saturday night. The spokesman said they are here mainly to take care of the relatives of those on board the missing flight.
