ANOTHER US CITIZEN HELD BY N. KOREA

SEOUL— North Korea detained a US citizen on Friday, South Korea’s Yonhap news agency reported, bringing the total number of Americans held by the rogue country to three. The man, a Korean-American in his fifties identified only by his surname Kim, had been in North Korea for a month to discuss relief activities, Yonhap said on Sunday. He was arrested at Pyongyang International Airport on his way out of the country. The man was a former professor at Yanbian University of Science and Technology (YUST), Yonhap said, citing unnamed sources. YUST, a university in neighboring China, has a sister university in Pyongyang. An official at South Korea’s National Intelligence Service said it was not aware of the reported arrest. Calls to YUST went unanswered. North Korea has in the past used detained Americans to extract high-profile visits from the United States.
