'Here I would also like to salute the civil society groups who have persisted in pursuing justice and compensation to those who suffered,' he said.

'Those affected by the catastrophe deserve our continuing support and sympathy. We owe it to our fellow citizens to put in place procedures and precautions to ensure that such a tragedy never occurs again.

'I share the grief of those affected by this horrible incident. I reaffirm our government's commitment to resolving issues of safe drinking water, expeditious clean up of the site, continuation of medical research, and any other outstanding issues connected with the Bhopal gas tragedy.'
