Authorities are searching for 11 people missing after a boat from Mexico capsized off Baja California. The U.S. Coast Guard and Navy are using aircraft and boats, with help from the Mexican Navy. The boat capsized in an area known for smuggling. Sixteen Mexican nationals were rescued Friday, including one treated for shark bites. Survivors said 27 people were on board.

The U.S. Coast Guard says it has rescued at least 16 people seen floating in the Pacific Ocean off Mexico’s Baja California coast and were searching for several others. The rescue took place before dawn on Friday. Petty Officer Chris Sappey said at about 1 a.m. several people were spotted floating in the water about 140 miles west of Ensenada. Sappey said it was unclear why people were in the water and no vessel has been found. He said one person who was rescued said as many as 27 people were on board a boat. Sappey had no further details about what the people were doing.
