No fewer than ten people have been confirmed dead after two navy helicopters collided in mid-air during a military training and rehearsal for a Royal Malaysian Navy parade.

According to BBC, one of the choppers clipped the rotor of the other before the two crashed down, leading to the death of at least ten persons.

Footage of the unfortunate incident which occurred on Monday night has been circulating on local media.

The choppers crashed in the Malaysian town of Lumut, which is home to a navy base.

“All victims were confirmed dead on site and the remains were sent to the [Lumut] Military Hospital for identification,” said the Royal Malaysian Navy.

One of the helicopters, a HOM M503-3 with seven people on board, was said to have crashed onto a running track.

While the other, a Fennec M502-6 conveying the other three victims, crashed into a nearby swimming pool.
