SAN DIEGO (AP) — Seven men and a pregnant woman clinging to a capsized boat have been rescued in Mexican waters off the coast of Tijuana.

The Coast Guard says the eight were picked up by a Canadian sailing vessel, the Island Princess, and taken to Shelter Island in San Diego.

U.S. Customs spokeswoman Jacqueline Dizdul says five of the men were taken to a hospital and treated for hypothermia. One also had a cut on his arm.

They claimed to be Mexican citizens, but authorities are working to confirm their statements.

It has not been determined whether the rescued group was planning to cross to the United States.
