The toxic legacy of the Vietnam War
The US has launched a multi-million dollar clean-up operation at an air base in Vietnam it used to store the notorious chemical Agent Orange.
The ten-year programme, unveiled more than four decades after the end of the Vietnam War, will cost $183m (£141m).
The site at Bien Hoa airport, outside Ho Chi Minh City, is considered the most contaminated in the country.
