"The cause of the plane crash is still under investigation. The company expresses its sorrowful condolences to the passengers and crew members who died in this plane crash," China Eastern airline said in a statement, according to CNN.
There were reportedly 123 passengers and 9 crew members on board.
"Our thoughts are with the passengers and crew of China Eastern Airlines Flight MU 5735. We are working with our airline customer and are ready to support them," Boeing said in a statement, CNN reported.
