"There were more than 580,000 bombing missions on Laos from 1964 to 1973 during the Vietnam War. That's equivalent to one bombing mission every eight minutes, 24 hours a day, for nine years. Over two million tons of ordnance was dropped on the country, with up to 30 per cent failing to explode as designed."

More than 40 years after the war, one-third of the country is still contaminated by unexploded ordnance — an ongoing cost of war that affects the Lao people daily.

There may be many other violations, but I think that's a credible start.
