South Korea has demanded an apology from North Korea over a landmine blast that injured three soldiers, saying they were hurt by North Korean mines on the southern side of the border.

Kang Hyun-woo, the director of operations at South Korea’s joint chiefs of staff, demanded an apology and “responsible measures” from Pyongyang over the blast, which occurred on 21 September during a search operation south of the border.
