"We can understand your sufferings at the hands of the attackers and the police," Clark, who along with Senator Sarah Flounders and a US trade union leader Steve Kirschbaun, visited BUPC refugees at the Brajamohan Tiwari High School relief camp, said.

"What is happening here, is happening in many places in the world. It is a government serving the rich at the cost of the poor. Your life and property are being taken away to set up an industry (chemical hub) without considering the disastrous Bhopal gas tragedy that took many lives," Clark said.

"We are from the US to get the first hand knowledge of the extent of exploitation in this part of the country," Clark said, adding that they would tell Americans about the sufferings of the people of Nandigram and mobilise public opinion.

The three, visiting Nandigram, are members of a Delhi-based human rights body, 'Anti-Imperialist Forum'.

Expressing solidarity with the victims, Clark said, "humanity is outraged. We shall resist the power of economic exploitation. We have to fight together and this requires unity."

He said that the killing of people, destruction of property and rapes at Nandigram was part of exploitation going on elsewhere in the world as a fallout of globalisation where the 'rich were getting richer at the cost of the poor'.

Kirschbaun said, "You are not alone, we are with you." Earlier, they met violence victims including a woman Shyamali Mondal of Sonachura, a 10-year-old boy, Bulu Mir, and a rape victim from Gokulnagar.

The refugee camp is being guarded by the CRPF.
