Giving an impetus to the ongoing struggle, Bollywood actor Aamir Khan [Images] will join both the protests on Friday to express solidarity with their cause.

"First Aamir will talk with two victims from both camps and hear about their plight. This will open up a larger discussion where students and journalists can interact and ask questions to the actor," Puneeta Roy of Tehelka Foundation, which is organising the meeting, told PTI.

Six of the Bhopal demonstrators will start their indefinite hunger strike on Tuesday demanding clean drinking water in the affected areas, criminal prosecution of the accused in the case, setting up of a National Commission on the issue, rehabilitation of victims and a ban on Union Carbide products, their spokesman Nityanand Jayaraman said.

Meanwhile, the Narmada Bachao Andolan activists continued their hunger strike in the capital even as their leader Medha Patkar remained in the CCU of a hospital in New Delhi.

Her condition is stable, her aides said. Support for NBA is also pouring in from the academic community with scholars including Romila Thapar, Bipan Chandra, Sumit Sarkar, Mushirul Hasan, Muchkund Dubey and Prabhat Patnaik writing to the PM asking him to ensure that the Supreme Court order is implemented in the case.
