Some of 16 survivors treated for suspected shark bites, US coastguard says.

The search continues for 11 people still missing after a boat capsized off Mexico’s Baja California coast on Friday, as multiple survivors have been treated for suspected shark bites, according to the US coastguard.

“Several of the individuals rescued were suffering from severe injuries consistent with shark bites, and the Coast Guard provided life-saving first aid while en route [to] San Diego,” the coastguard said in a statement on Saturday.

Sixteen Mexican nationals were rescued on Friday. Survivors told officials there were 27 people on board.

The coastguard and US Navy used multiple aircraft and boats, along with assistance from the Mexican Navy, to search the area for the remaining passengers. An additional helicopter will be deployed later on Saturday, according to the coastguard.

A Mayday call was transmitted from someone on the boat at about 1am on Friday, coastguard Lieutenant Santiago Tamburini said on the day.

A rescue helicopter reached the site about two hours later. It took about 90 minutes for the crew, which included a rescue swimmer, to pull the 16 people from the water, he added.

The boat went down about 225km (140 miles) west of Ensenada, Mexico, an area popular with fishing and leisure boats, but that is also frequented by smugglers.

Although the incident did not happen in US waters, coastguard official Charlie Valor said on Saturday they “were able to help, and that’s why we launched our assets”.

Fatal attempts to transport refugees and migrants from Mexico to the US have occurred in the past.

In May 2025, at least three people died when a boat flipped off the coast about 56km (35 miles) north of the US-Mexico border.

In 2023, eight people were killed in one of the deadliest maritime smuggling accidents off the US coast, when two boats approached a San Diego beach in heavy fog, and one capsized in the surf.
