Srinagar, April 23 (KNS): Two Malaysian military helicopters collided and crashed during a training session on Tuesday, killing all 10 crew onboard, reports said.

According to reports, the helicopters were participating in a flypast rehearsal ahead of Naval Day celebrations in May.

One chopper was seen clipping the rear rotor of another, causing both to go into a tailspin and crash.

"The two helicopters collided during flight training," they said, adding that all 10 crew members on board were confirmed dead by medical officers.

The two aircraft involved were a Eurocopter AS555SN Fennec and an AgustaWestland AW139, they said.

Photos showed the Eurocopter model heavily mangled in the wreckage on the naval base stadium track with rescue personnel surrounding it as well as various debris.

The AgustaWestland helicopter crashed at the naval base's swimming pool area. (KNS)
