Film star Aamir Khan Friday turned environmental activist as he strongly came out in support of evacuees of the Narmada dam and the victims of the Bhopal gas tragedy who have been protesting here demanding rehabilitation and adequate compensation.

"I do not know about the issue completely so I would not like to comment on whether the height of the dam should be raised or not.

But what I know is that thousands of people have been affected due to the building of the dam (in western India) and they have not been given proper rehabilitation by the government," said the film star, who was mobbed by the media and a large crowd that came to see him in his new avatar.

"This is an emotional reaction after seeing the struggle of the activists," he said about his presence among the activists at the Jantar Mantar near the business district of Connaught Place.

He added: "I was not aware of the agitation of the two groups but last week when I was in Delhi, I saw these people sitting at the Jantar Mantar and came to know about them."

Khan was accompanied by his co-stars and director of the recently released hit film "Rang De Basanti".

"I wanted to come and meet them, and I also asked my friends to come and support the cause for which these activists have been on fast for so many days," he said.

The star's support for the Narmada Bachao Andolan (NBA) activists came a day before the cabinet is expected to meet and discuss the issue.

A fact-finding team sent by the government to visit the villages in Gujarat, Madhya Pradesh and Maharashtra that would be affected due to the construction of the dam has returned and is expected to present its report at the cabinet meeting.

Well-known environmental activist Medha Patkar has been on an indefinite hunger strike since March 29 against the raising of the height of the Sardar Sarovar Dam. The activists of NBA allege that over 35,000 people, displaced by the dam, have not been rehabilitated.

Khan also appealed to Prime Minister Manmohan Singh to give the protesters proper attention and time so that they can present their problems before him.

"I request the prime minister to give them proper rehabilitation and compensation according to the norms. Every Indian in the country has the right to get proper food, land and employment and the government should give these people the kind of agricultural land promised to them and source of employment," he said.

"The farmers who have been displaced should be rehabilitated well by the government and this should happen in absolute terms and not just on paper. We know there is corruption in the society and we must come together in support of the activists," he said.

Khan added: "I have come here for the sake the farmers who give us food to eat and it is the responsibility of the government to rehabilitate these people," said Khan.

Speaking in support of the victims of the Bhopal gas tragedy of 1984, the actor said that people have been demanding basic rights like safe drinking water and compensation, which they have not been given by the government even though it has been over 20 years of the tragic incident.
