SEOUL (AFP) - North Korea seized a resort jointly run with the South on Monday, state media reported, in a move likely to ramp up tensions even as Pyongyang seeks to ease relations with the wider world. The isolated communist state ordered all S Koreans to leave the Mount Kumgang resort and said it was taking control of all assests there. The move comes as Pyongyang has begun making overtures to the United States after years of sabre-rattling punctuated by missile tests and the detonation of two atomic bombs which saw North Korea thrust deeper into intl purdah. It also coincides with a visit to Russia by reclusive dictator Kim Jong-Il, who is seeking food aid from Moscow to alleviate growing shortages.
