Victims of the 1984 Bhopal gas tragedy, whereby a gas leak from a Union Carbide pesticide plant killed at least 3,500 people, attend a demonstration in New Delhi July 26, 2010. Hundreds of survivors of the accident took part in the protest on Monday demanding that the government revisit its recent decisions on issues of compensation, rehabilitation of victims and take legal action against U.S. chemical firm Union Carbide and its parent company Dow Chemicals, according to non-governmental organisations (NGO) "Bhopal Group for Information and Action" and "Children against Dow-Carbide".
