Three South Korean soldiers injured by landmine explosions in border zone

Three South Korean soldiers were hurt by landmine explosions in the Demilitarized Zone on September 21. Two blasts occurred on the South Korean side of the DMZ, the heavily fortified strip of land that separates the two Koreas. South Korea's military said the mines were most likely planted by North Korea. South Korea called the explosions a violation of the 1953 armistice agreement and demanded an apology. It also warned of "corresponding measures" if North Korea's responsibility is confirmed. North Korea denied the findings and threatened to retaliate if South Korean troops fired on its soldiers working at the border. The two countries have no working military hotlines, and the UN said it was handling the violation through official channels.
