A China Eastern Airlines passenger jet with 132 people on board crashed in the mountains of southern China on Monday while on a flight from the city of Kunming to Guangzhou, China's Civil Aviation Administration of China (CAAC) said.
The jet involved in the accident was a Boeing 737 aircraft and the number of casualties was not immediately known, state broadcaster CCTV said. Rescue services were on their way to the scene, it said. There was no word on the cause of the crash.
The plane was a 6-year-old 737-800 aircraft, according to Flightradar24.
The CAAC said the aircraft lost contact over the city of Wuzhou. It had 123 passengers and nine crew on board. State media said earlier there were 133 people on board.
"The CAAC has activated the emergency mechanism and sent a working group to the scene," it said in a statement.
Media cited a rescue official as saying the plane had completely disintegrated. A fire sparked by the crash burned down bamboo and trees before being put out.
The flight departed the southwestern city of Kunming at 1:11 p.m. (0511 GMT), FlightRadar24 data showed, and had been due to land in Guangzhou, on the south coast, at 3:05 p.m. (0705 GMT).
The plane had been cruising at an altitude 29,100 feet at 0620 GMT, according to FlightRadar24 data. Just over two minutes and 15 seconds later, the next available data showed it had descended to 9,075 feet. In another 20 seconds, its last tracked altitude was 3,225 feet.
