MIAMI -

The U.S. Coast Guard has repatriated 46 Cuban migrants who were interdicted at sea in two separate cases this week.

Officials say the first group of 29 Cubans was stopped Saturday aboard a 15-foot raft south of Key West. The second group of 17 aboard a boat was also interdicted near Key West on Sunday.

Both groups were later placed aboard the 154-foot Coast Guard Cutter William Flores and were taken back to Cuba on Thursday.

Under the federal wet foot/dry foot policy, Cubans who are caught at sea are generally returned to the communist island while those that reach U.S. shores are usually permitted to stay.
