Seoul said Thursday it had deployed a warship to Libya to secure the release of a South Korean national kidnapped along with three Filipinos in the North African country. The 4,000-ton vessel, Munmu the Great, which takes part in anti-piracy operations in the Gulf of Aden, was now on its way to Libya. In addition to “carrying out its duty of protecting commercial vessels, [the warship] is also preparing for all possibilities including the need for military support,” a defense ministry spokesman told AFP.
