SEOUL, South Korea – North Korea has announced it detained another American citizen over unspecified hostile acts against the country. North Korea's official Korean Central News Agency said Sunday that Kim Hak Song had worked for the Pyongyang University of Science and Technology before he was held on Saturday. North Korea on Wednesday announced the detention of an accounting instructor at the same university, Kim Sang Dok, for "acts of hostility aimed at overthrowing the country." The KCNA didn't say whether the two cases are connected.
