Bhopal 25 years later: still seeking justice

On Dec. 3, 1984, 40 tons of poisonous gases escaped the Union Carbide factory in Bhopal, India. Thousands of people died. The Union Carbide factory is now abandoned and Union Carbide a subsidiary of chemical giant Dow, but the leak’s effects on Bhopal still linger in contaminated water supplies and the chronic illnesses of survivors. BBC correspondent Allan Little returned to the Indian city on the 25th anniversary of the disaster and talked to residents still looking for justice.
