Thousands protested in India Saturday against the country's decision to compete in the London Olympics despite sponsorship of the Games by a US firm linked to the 1984 Bhopal gas tragedy. Marking the 27th anniversary of the industrial disaster which killed tens of thousands of people, protestors gathered at two sites in the central city of Bhopal to demand India pull out from the Games, which are sponsored by Dow Chemical. Dow Chemical bought Union Carbide, the firm blamed for the lethal gas leak, a decade after the company had settled its liabilities with the Indian government by paying $470 million for Bhopal victims. "This protest is against both the Olympics and government indifference towards gas victims," activist Rachna Dhingra of the Bhopal Group for Information and Action told a foreign news agency.
