Investigators in China have ruled out terrorism in the crash of a passenger plane Sunday that claimed the lives of 54 people.
State media said Monday that investigators sent from Beijing hadn't determined the cause of the crash but found no evidence of sabotage.
The China Eastern Airlines Shanghai-bound jet plunged into a lake just seconds after taking off from Baotou city in Inner Mongolia.
Witnesses said they heard a blast while the plane was still in the air. All 53 people on board and one on the ground were killed.
Divers have yet to find the two in-flight recorders that could help determine the cause of the accident.
The plane was a Canadian-made CRJ-200. China has grounded all its other CRJ-200s.
