SEOUL: The possibility that an entity other than Iran was responsible for the attack against a South Korean cargo vessel near the Strait of Hormuz is low, a senior official in Seoul was quoted as saying by the Yonhap news agency on Thursday. South Korea is analizing intelligence shared by the US on the May 4 attack against South Korean shipper HMM’s Namu vessel, which caused a fire and damaged the lower stern hull, Yonhap quoted a senior foreign ministry official as telling reporters.
