PARIS — Pirates freed 20 hostages aboard a Turkish freighter commandeered off the Somali coast, as nine captives on a French boat were released off southern Nigeria, the boat owners said Wednesday.

The Yasa Holding Co. said pirates freed the Yasa Neslihan freighter Tuesday after paying a ransom. The Turkish ship was seized Oct. 29 in the Gulf of Aden, which connects the Red Sea to the Indian Ocean near Somalia.
