North and South Korea exchange gunfire at border: Seoul

The Demilitarized Zone dividing North and South Korea is one of the most fortified places in the world

North Korean troops fired multiple gunshots towards the South in the Demilitarized Zone dividing the peninsula on Sunday, prompting South Korean forces to fire back, Seoul said.

The rare exchange of gunfire comes a day after North Korean state media reported that leader Kim Jong Un had made his first public appearance in nearly three weeks following an absence that triggered intense speculation about his health and fears about the stability of the isolated nation.
