North Korean army vows to cut off road, railway links with South Korea

North Korea’s army has vowed to cut off road and railway links between North and South Korea, starting Wednesday. A statement from the organization says this comes as a response to war exercises that were held in the “the primary hostile state” of South Korea — the North’s “invariable principal enemy.” North Korea installed landmines and barriers along the border in the months prior, according to South Korea’s military.
