On the 20th anniversary of the gas leak disaster in Bhopal, India, Scottish green and human-rights organisations have called on the US government to take action against those responsible.
Friends of the Earth Scotland, Amnesty International, WDM Scotland, Jubilee Scotland and the Centre for Human Ecology delivered a letter to the US Consulate General urging action against US company Dow Chemical.
Campaigners believe as many as 20,000 people have died as a result of the leak of methyl isocyanate from Union Carbide's plant in 1984. They say the compensation agreed in 1989 by the firm, later bought by Dow, was inadequate.
Duncan McLaren, chief executive of Friends of the Earth Scotland, said: "No-one has been held to account for the disaster."
