Plane with 132 passengers crashes in southern China: state TV report

A  China Eastern Airlines plane with 132 passengers has crashed, creating a fire in mountains in the Guangxi region in southeast China.

State television first reported the incident on Monday.

The U.S. National Transportation Safety Board announced on Twitter that it has "appointed a senior air safety investigator as a U.S. accredited representative" to investigate the crash.

While China's Civil Aviation Administration will lead the investigation, the U.S. safety board said that "representatives from Boeing, General Electric and the Federal Aviation Administration will serve as technical advisors."

Initial reports stated that 133 people were onboard, but China's CGTN now reports 132 passengers were on the plane.

Chinese state TV said that a Boeing 737-800 traveling from Kunming to Guangzhou ended up crashing near the city of Wuzhou.

Casualties remain unknown and rescue operations are underway, the state outlet said.

It is unclear what caused the crash.
