The U.S. Coast Guard reported on Thursday that 2 people were killed and 10 others were believed to be missing from a boat that capsized off Key West, Florida.

Coast Guard spokesman Petty Officer Jose Hernandez said 8 survivors from the wreck were pulled from the water 18 miles southwest of Key West by crew members of a Coast Guard cutter on patrol in the area at about 1 PM.

Hernandez pointed out that 2 bodies also were recovered. Coast Guard teams continued to scourge the area by aircraft and vessels for 10 people who, according to the survivors, were unaccounted for after the boat flipped, the spokesman told Reuters by phone.

Hernandez said he had no information on the size or type of the boat, how it capsized, or if weather conditions may have been a factor in the mishap.

He added that he was not aware of what the stricken boat or its occupants were doing at the time of the incident. The survivors told Coast Guard officials the mishap occurred in darkness, he said.

Also on Thursday, the Coast Guard repatriated 8 Cuban migrants who were intercepted off the coast of Islamorada in the Florida Keys last week while trying to cross the Florida Strait in a raft. Around 300 Cuban migrants have been likewise interdicted since last October, according to the Coast Guard.
