One-third of the bombs dropped on Laos remained unexploded after the war ended in 1975, and these unexploded bombs killed 20,000 Laotians over the following three decades.
Notes on verification
Multiple independent, credible sources (MAG International, HALO Trust, NBC News, Al Jazeera citing Landmine Monitor) corroborate both the ~one-third unexploded ordnance figure and the 20,000 casualties since 1975, though some sources use 'killed or injured' rather than strictly 'killed,' introducing minor ambiguity.
