Memories of the Bhopal disaster - 25 years on

Twenty five years ago in the Indian city of Bhopal, a cloud of toxic gas leaked from a pesticide factory. Within three days, 8,000 people were dead.

Thousands more have died or been badly affected since.

Local people, backed by two recent studies, say the plant is still leaking dangerous toxins into the city's drinking water.
