In the early hours of a December morning in 1984, toxic gas leaked from the Union Carbide plant in Bhopal, India.
Thousands were killed, and many more suffered permanent serious injury. The company was later bought by Dow Chemicals, which is now an official sponsor of the Olympic games.
Some like former Olympic Hockey player Aslam Sher Khan are calling for an Indian boycott of the games.
He said: “It is a matter of great shame. That when sports organisations around the world are standing up for the victims of Bhopal and 25 members of the British House of Commons are protesting, India itself is taking the matter so lightly. Twenty five thousand people died and it makes no difference in this country. This matter is connected to the Olympics because that is a forum where we can talk with other countries.”
Jagbir Singh also represented his country in Hockey at the 1988 and 1992 Olympic Games, and thinks it is too much to ask athletes to not attend the games.
He said: “No player can think of boycotting a dream as cherished as the Olympics, however the pain of those who have suffered makes me think that the Olympic committee must look into the matter.”
The Olympic Committee has defended the Dow Chemicals sponsorship deal, as its links to Union Carbide came long after the accident.
