North Korea Says It Will Cut Communication Channels With South Associated Press SEOUL, SOUTH KOREA - North Korea said Tuesday it will cut off all communication channels with South Korea as it escalates its pressure on the South for failing to stop activists from floating anti-Pyongyang leaflets across the border. The North Korean warning came as relations between the two Koreas have been strained amid a prolonged deadlock in broader nuclear diplomacy between Pyongyang and Washington. Some experts say North Korea may be deliberately creating tensions to bolster internal unity or launch bigger provocation in the face of persistent U.S.-led sanctions. The North's Korean Central News Agency said Tuesday that all cross-border communication lines will be cut off at Tuesday noon. It said it will be "the first step of the determination to completely shut down all contact means with South Korea and get rid of unnecessary things." "The South Korean authorities connived at the hostile acts against (North Korea) by the riff-raff, while trying to dodge heavy responsibility with nasty excuses," it said. "They should be forced to pay dearly for this." Since last week, North Korea has increasingly expressed its anger over the leafleting by threatening to permanently shut down a liaison office with South Korea and a jointly run factory park, as well as nullify a 2018 inter-Korean tension-reduction agreement. North Korean citizens have also staged a series of mass anti-Seoul public rallies, something the North typically organizes in times of tensions with the outside world. .
