Scores of mortar shells and butterfly bombs were recently found again at the construction sites around the Nam Gate of Kaesong and Kwandok Pavilion and a rusted machine-gun bullet lodged in Yonbok Temple Bell, one of five famous bells of Korea.

In the area of Kaesong alone, more than 20 historical relics of national treasure were severely destroyed by the U.S. imperialist air raids during the war.
