Two military helicopters collided in mid-air before crashing and killing at least 10 people in Malaysia this morning.

The choppers were among seven that had taken off simultaneously from the the Royal Malaysian Navy (TLDM) Base in Lumut, Perak, Tuesday, April 23, shortly after 9 am local time.

But the footage shows how two of the touched rotors at a height of around 200ft - sending both aircraft hurtling to the ground in deadly tailspins.

One helicopter crashed onto a running track and burst into flames. The other is understood to have come down on the edge of the stadium.

Local media reported that as many as 10 people died, consisting of seven crew members and three passengers.

The accident occurred during training ahead of the TLDM's 90th anniversary celebrations.

The two helicopters involved in the collision were HOM and Fennec models. The HOM helicopter was carrying four crew and three passengers, while the Fennec was carrying three crew.
