Both North and South Korea violated the armistice that governs their shared border by sending drones into each other's airspace in December, the U.S.-led United Nations Command (UNC) said on Thursday.
Five North Korean drones crossed into the South on Dec. 26, prompting South Korea's military to scramble fighter jets and helicopters as well as send surveillance aircraft into the North to photograph its military installations.
The U.N. command, which has helped oversee the Demilitarized Zone (DMZ) between the two Koreas since an armistice ended fighting in the 1950-1953 Korean War, conducted a special investigation of the airspace incursions to determine whether there were any violations of the armistice.
