A US Marine Corps aircraft with four people on board crashed in northern Norway Friday while participating in a NATO exercise several hundred miles from the Russian border, officials said, the New York Post reported.

The MV-22B Osprey was reported missing around 6:30 p.m. local time. A rescue helicopter and Norwegian military plane spotted the wreckage, according to Norwegian officials.

“We’ve seen no sign of life,” Nordland police chief of staff Bent Eilertsen said.

Air rescue efforts were thwarted by bad weather conditions, and a ground response was underway, according to officials.

The US Marines confirmed an “incident” involving an MV-22B Osprey aircraft in a statement.

The airplane-helicopter hybrid was taking part in a NATO drill entitled “Cold Response” when it was reported missing.
