The U.S. Coast Guard has repatriated 32 Cuban migrants who were recently picked up in waters off South Florida and the Keys.

A cutter dropped off the migrants Thursday in Bahia de Cabanas, Cuba. They had been interdicted in three different cases since April 12.

Officials say 13 migrants were picked up April 12 after a Carnival cruise ship reported a rustic vessel near Key West. The same day, a Coast Guard ship picked up another 17 migrants, also near Key West. Last Tuesday, seven Cubans were picked up near Key Biscayne, Fla.

According to a Coast Guard release, five of the 37 migrants were transferred to Customs and Border Protection. The Coast Guard didn't say why.
