Addressing press conference here, the Chief Minister said, "Without simultaneous operations in Jharkhand, it will be difficult for the (Bengal) police to hold on to the gains."
He also pointed out that security forces should start operations in other parts of the state, especially those bordering Jharkhand, where Maoist strongholds are located.
Bhattacharjee said the extremists were attacking and killing innocent people, police personnel and government servants 'creating serious problems'.
"We have achieved some gains in the last few months...We are now dominating the areas of West Midnapore, Purulia and Bankura. By dominating, we mean that the police is functioning normally, the administration is functioning almost as usual. But there are sporadic incidents," the Chief Minister added.
