A quarter of a century has passed since Bhopal suffered the world's worst industrial disaster, but its legacy lingers.

At least 2,000 people died that night, according to government figures - aid organisations estimate 5,000 died in the first 72 hours, and a further 15,000 in the following weeks.
Of the living, at least 100,000 are chronically ill from their exposure to the toxic gas, and a further 30,000 are still drinking and washing in contaminated groundwater.
