The destroyer Choi Young and the Samho Jewelry, an 11,500-ton vessel carrying chemicals, are expected to arrive in Salalah, Oman, next week, South Korea's Yonhap News Agency reported. The five prisoners are under guard on the Choi Young, while the bodies of eight pirates killed in the operation are in a refrigerator.
Several commandos remained on board the Samho Jewelry to ensure its safety.
None of the commandos or the 21 crewmembers on the Samho Jewelry were killed, although the captain of the cargo vessel was wounded in the raid Friday.
South Korean authorities are trying to determine where the pirates should be tried.
