Military plane crashes in California, several dead

A US Marine Corps plane crashed in southern California yesterday. At least four people on board were killed, the Los Angeles Times reported.

The US Navy has confirmed the accident on Facebook, but has not yet disclosed any casualties. According to the Navy, there were five people on board.

The accident happened near the town of Glamis, about fifty kilometers from the border with Mexico. Initially, there were reports that the aircraft had radioactive material on board, but the navy denies this.

The plane that crashed is an MV-22B Osprey, a propeller-driven aircraft that can land and take off vertically, like a helicopter, by rotating its engines. In March, a similar US military plane crashed in Norway. Four Marines were killed.

The US military commissioned the Osprey in 2007. Eight planes have since crashed, according to the Los Angeles Times .
