Ten people have been killed after two Malaysian Navy helicopters collided in midair and spiralled to the ground on Tuesday.

Footage captured the shocking moment of impact as one chopper clipped the other’s rotor before they plummeted.

The two aircraft were among several involved in a rehearsal for a parade celebrating the 90th anniversary of the Royal Malaysian Navy, to be held on Saturday.

All 10 victims were crew aboard the aircraft involved in the accident.

It happened at the Lumut naval base in the western state of Perak at 9.32am on Tuesday, the navy said in a statement.

“All victims were confirmed dead at the scene and sent to the Lumut army base hospital for identification,” the navy said.

The navy said it would investigate the cause of the accident.

Defence Minister Mohamed Khaled Nordin said efforts were under way to verify the identities of the crew members killed. All were younger than 40.
