Three US Marines died on Sunday after an Osprey aircraft crashed on a remote tropical island north of Australia during war games, according to US military officials. The crash occurred during a training exercise and resulted in the deaths of three Marines. Five other Marines were rescued from the crash site and flown to a hospital in Darwin for treatment. They are currently in a serious condition. The cause of the crash is under investigation. The Osprey is a tiltrotor aircraft that combines the functionality of a helicopter and an airplane. It is commonly used by the US Marine Corps for various missions. The US military has temporarily halted the use of Osprey aircraft following the crash.
