More than two dozen Cuban migrants missing after boat sinks in Florida

More than two dozen Cuban migrants were missing Wednesday after their boat sank in the waters off the Florida Keys as Hurricane Ian neared the area.

The chief border patrol agent for Miami, Walter N. Slosar, said his agents responded to a migrant landing on Stock Island in the Florida Keys, about two hours before the hurricane made landfall on the southwest coast of Florida.

Four Cuban migrants swam to shore after their vessel sank due to inclement weather, Slosar said in a tweet, adding that the Monroe County Sheriff's Office also responded.

A U.S. Customs and Border Protection spokesman told NBC News in an email that four individuals are receiving care and treatment, adding that the incident remains under investigation.

With 20 others still missing, the Seventh Coast Guard District initiated a search and rescue operation.

Three people were rescued by Coast Guard crews about 2 miles south of Boca Chica at 3: 30 p.m.

The Seventh Coast Guard District said on Twitter that they were brought to a local hospital for symptoms of exhaustion and dehydration.

Air crews are still searching for the remaining missing migrants.
