Pyongyang's military

Barricades are seen at a military checkpoint on the Tongil bridge, the road leading to North Korea's Kaesong city, in the border city of Paju on Oct. 15, 2024.

North Korea blew up sections of the deeply symbolic roads connecting it to the South on Tuesday, Seoul's military said, adding it had conducted a "counter-fire" operation in response.

North Korean leader Kim Jong Un would face the end of his regime if he ever used his isolated country's nuclear weapons against the South, Seoul's president said on Tuesday.
