KUALA LUMPUR, APR 23 (AFP/APP/DNA): Two Malaysian military helicopters collided and crashed during a training session on Tuesday, killing all 10 crew onboard, the country’s rescue agency said.

Footage shared online showed several helicopters flying low in formation over the Lumut naval base, located about 160 kilometres (100 miles) from the capital Kuala Lumpur.

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,” said Suhaimy Mohamad Suhail, senior operations commander from the fire and rescue department, 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 Agusta Westland AW139, the rescue agency 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 Agusta Westland helicopter crashed at the naval base’s swimming pool area.
