SEOUL: A South Korean fishing vessel was apparently hijacked in waters off Somalia on Saturday, a defense ministry official said. “The boat sent a message that she was being approached by some unidentified vessels, the South Korean official told Agence France-Presse. Contact with the fishing boat was then lost, he said. South Korea’s naval anti-piracy unit, which was on routine patrol off Somalia, was urgently dispatched to the site, the official added. The fishing vessel was carrying an unknown number of crew members, including South Koreans and foreigners, he said. Somali pirates hijacked an Iranian fishing boat with a crew of up to 20 on Tuesday. They took the captured vessel to a port in northern Somalia, John Steed, regional manager for Oceans Beyond Piracy, a US-based non-profit group, said Wednesday. There have been at least eight attacks by Somali pirates in recent months and three successful hijackings.
