PHOENIX (AP) — An official at Davis-Monthan Air Force Base in the U.S. says two Chinese sailors died and six are believed to be missing after their boat sank in the Pacific Ocean.

Maj. Sarah Schwennesen said Sunday that a Venezuelan fishing boat reported finding 11 sailors floating in a raft Friday afternoon.

She says the Venezuelan crew said four sailors were badly burned and two later died of their injuries.

Airmen from the 563rd Rescue Group treated the injured sailors Saturday and into Sunday morning.

Schwennesen says the boat is expected to get close enough to shore by Monday morning for helicopters to hoist the injured sailors and fly them to Cabo San Lucas, Mexico. They will then be taken to a burn unit in San Diego.
