South Korea's military has demanded an apology from North Korea for landmine explosions on September 21 in the Demilitarized Zone (DMZ) that injured three soldiers. North Korean leader Kim Jong Un's sister, Kim Yo Jong, dismissed the assessment as a "conspiratorial farce." The United Nations Command (UNC) confirmed on Wednesday that it identified a North Korean anti-personnel mine on the South Korean side of the Military Demarcation Line, determining it to be an Armistice Agreement violation.
