Warren Anderson, chief of Union Carbide during 1984 Bhopal disaster, is dead at 92

Warren M. Anderson, who headed Union Carbide Corp. when a chemical leak killed thousands of people in India in 1984, has died in Florida at 92.

Anderson's death was not announced but was confirmed Friday by The Associated Press through public records. The records say Anderson died at a nursing home in Vero Beach, Florida, on Sept. 29. No cause of death was given.

Anderson ran Union Carbide in December 1984 when a pesticide plant run by a subsidiary leaked about 40 tons of deadly gas into the air of the Indian city of Bhopal, killing about 4,000 people.

Many more died in the following months, bringing the estimated death toll to 15,000.

The Indian government says at least 500,000 people were affected through either direct injuries or birth defects.
