North Korea blows up liaison office on its side of border with South

North Korea blew up an office set up to foster better ties with South Korea in its border town of Kaesong on Tuesday after it threatened to take action if North Korean defectors went ahead with a campaign to send propaganda leaflets into the North.

North Korea's KCNA state news agency said the liaison office, which had been closed since January over fears of the novel coronavirus, was "tragically ruined with a terrific explosion".
