The Home Ministry has asked paramilitary forces and state governments to take all necessary measures to ensure that the third phase of Lok Sabha polls tomorrow passes off peacefully.
A senior Home Ministry official said over 15,000 polling stations spread over ten parliamentary constituencies in Bihar and West Bengal have been classified as those falling in Naxal-affected areas.
"We cannot be complacent. We are taking necessary actions," he said, adding appropriate security arrangements have been made and the priority is to ensure that the polls are held smoothly and efforts to disrupt the democratic process foiled.
As many as 19,763 villages have been identified as vulnerable to intimidation of voters and 45,843 persons would be kept under watch in these areas.
Sources said central security forces have been instructed to keep a close watch on the prevailing situation in the troubled states.
While the first phase on April 16 saw large scale violence, the second phase on April 23 passed off by and large peacefully.
