Police say an Indian air force helicopter has crashed in the country's remote northeast bordering China, killing all seven people on board, including the crew members.

The police control room says that the crash occurred on Friday in mountainous Tawang area in Arunachal Pradesh state.

The cause of the accident was not immediately known. The air force helicopter took off from an army helipad in the area.
