Bhopal, India, June 07, 2010, SPA -- A court on Monday found the Indian unit of U.S. chemicals firm Union Carbide and seven Indian employees guilty of negligence over one of the world's worst industrial accidents that killed thousands of people in 1984. Union Carbide plant in the central city of Bhopal accidentally released toxic gases into the air and the government says around 3,500 people died as a result. Activists say 25,000 died in the immediate aftermath and the years that followed, Reuters reported. The verdict is the first in more than 25 years that could lead to jail sentences of up to two years and fines for those convicted, though rights activists said the punishment would be too light. Keshub Mahindra, current chairman of India's top utility vehicle and tractor maker Mahindra & Mahindra, was the highest ranking person convicted on Monday. He was chairman of Union Carbide India Ltd, a unit of Union Carbide, at the time of the accident. Union Carbide's Indian arm was also found guilty. Those convicted can appeal to a higher court, a process that in India can take years. --SPA 12:08 LOCAL TIME 09:08 GMT www.spa.gov.sa/789710
