The Lao People’s Democratic Republic is the world’s most heavily unexploded ordnance-contaminated nation, deeply affecting the country’s people. During the Second Indochina War (also known as the Vietnam–American War), the United States carried out more than half a million bombing missions over Lao PDR, during which over two million tons (1.8 million metric tonnes) of ordnance were dropped. Up to 30 percent of this ordnance failed to explode,leaving behind a serious UXO contamination that still kills and maims innocent men, women and children in one of the poorest nations in the world.
