KUALA LUMPUR, Malaysia—Two Malaysian military helicopters collided midair and crashed during a training session on Tuesday, killing all 10 people on board and injuring a swimmer in a pool, authorities said.
The helicopters were rehearsing at a naval base in northern Perak state for the navy’s 90th-anniversary celebration when the accident occurred, the navy said in a brief statement. “All victims were confirmed dead on site,” it said.
