Rescuers were still searching on Saturday for 11 people missing after a boat capsized off Mexico's Baja California coast, the US Coast Guard said.

Sixteen Mexican nationals were pulled from the water on Friday after a mayday call at about 1:00am. A rescue helicopter reached the scene about two hours later, and it took the crew about 90 minutes to lift the 16 people aboard, Coast Guard Lieutenant Santiago Tamburini said.

The Coast Guard said several of those rescued had severe injuries consistent with shark bites and were given first aid on the way to San Diego. Three people were taken to Scripps Mercy Hospital San Diego, including one with a suspected shark bite and two treated for cold exposure, a hospital spokesperson said.

Survivors told officials there were 27 people on board. The boat went down about 225km (140 miles) west of Ensenada, an area popular with fishing and leisure boats that is also used by smugglers.

The Coast Guard and US Navy joined the search with aircraft and boats, helped by the Mexican Navy. The incident did not happen in US waters; a Coast Guard official said the service helped because it was able to. The US Customs and Border Protection agency is interviewing survivors, and the Mexican consulate in San Diego said all those rescued were Mexican nationals.

Past attempts to carry migrants from Mexico to the United States by sea have ended in deaths. In May 2025, at least three people died when a boat flipped off the coast north of the US-Mexico border, and in 2023 eight people were killed when one of two boats capsized near a San Diego beach.
