World: Asia-Pacific In pictures: Images of war
Years of bitter revolutionary struggle culminating in the American secret war between 1964 and 1973 have left Laos as the most bombed country in the history of warfare.
Laos was officially neutral but became a major battlezone throughout the Indochina wars
The Pathet Lao and their North Vietnamese allies used the Plain of jars as a key strategic staging area
American military planners were determined to stop the rise of communism in South-East Asia
Pilots returning from raids over Vietnam would often clear bomb bays over Laos to comply with orders to release all bombs
Cluster bombs scattered millions of lethal bomblets across the countryside
The whole of Laos became a free fire zone
