Bhoori Bi (R) poses for a picture with her daughter Chandni in an undated family photograph in Bhopal. Bi said that Chandni died as a result of gas poisoning after the 1984 Bhopal disaster. On the night of December 2, 1984, the factory owned by the U.S. multinational Union Carbide Corporation accidentally leaked cyanide gas into the air, killing thousands of largely poor Indians in the central city of Bhopal.
