South Korea fires warning shots at a North Korean drone that flew several hundred yards south of the border between the two countries. The drone turned back into North Korea and was not hit by the warning shots.
North and South Korea exchange artillery fire across their mutual border. After North Korean soldiers fire several shots at a military loudspeaker that speaks in high voice against Pyongyang, South Korean troops return ‘dozens of shells” to the suspected source. No casualties are reported. North Korea later warns Seoul in a letter that it will take military action if the South did not stop the loudspeaker broadcasts within 48 hours. In a separate letter, Pyongyang says it is willing to offer an opening to resolve the conflict even though it considers the broadcasts a declaration of war.
