(Newser) – A Marine who ejected from an airplane over the Persian Gulf is "presumed lost at sea," the US Navy says, marking the first reported casualty from the ongoing operation against ISIS in Iraq and Syria. The Marine and another crew member ejected from an MV-22 Osprey when the aircraft lost power and it appeared it might crash after takeoff Wednesday from the USS Makin Island, the Navy says.

The pilot of the Osprey regained control of the aircraft and safely landed it aboard the Makin Island while rescuers recovered the other crew member from the water, the Navy says. "US Navy, Marine Corps, and Coast Guard personnel conducted an extensive search of the area using all available assets, which continued throughout the night and the next day," the Navy said in a statement. The Navy says the Marine's name will be withheld pending the notification of the troop's family, and the Navy and the Marine Corps will investigate the cause of the incident.
