SEOUL, South Korea—In the latest blow for inter-Korean cooperation, North Korea threatened to permanently shut a liaison office with South Korea as it continued to condemn its rival for failing to prevent activists from sending anti-North Korean leaflets across the border.
The statement by North Korea’s ruling Workers’ Party late on June 5 came a day after the powerful sister of leader Kim Jong Un said her country would end a military agreement reached with South Korea in 2018 to reduce tensions if Seoul fails to stop the activists.
