On the 27th anniversary of the Bhopal gas tragedy on Saturday, victims and survivors, still waiting for relief, will register their protest by launching an indefinite rail roko andolan (stop trains).

“On December 3, please don't travel by train. Change your reservations now. We are sorry to cause you inconvenience but stopping the trains is the only effective way we can think of to get our urgent and important message through to the Prime Minister and the government,” read a notice on the Bhopal.net website, which is endorsed by five survivor organisations.
