MIAMI (AP) - The U.S. Coast Guard has returned to Cuba 25 migrants found floating off Florida shores.

The migrants were interdicted at sea in three separate incidents last week.

The Coast Guard says two migrants were spotted Friday floating on a plastic foam raft about 8 miles east of Islamorada. A Coast Guard plane spotted 19 Cuban migrants about 30 miles north of Mariel, Cuba, on Wednesday and directed a cutter to them. Also on Wednesday, U.S. Customs and Border Protection plane spotted four migrants aboard a raft about 17 miles east of Sands Cut.

All the migrants received food, water, shelter and medical care aboard Coast Guard vessels.
