Under attack from several chief ministers, including UPA ally Mamata Banerjee, on NCTC, Home Minister P Chidambaram on Monday said there was no conflict between the central and state agencies and they worked together on the ground to deal with terrorsts.

Addressing a conference of chief ministers on internal security, Chidambaram said in 2011, 18 terror modules were neutralised and 53 persons arrested and in the first three months of 2012, three modules were neutralised and 11 persons arrested.

"I wish to underline the fact that one-half of the cases were cracked through the joint efforts of the central agencies and state police concerned. This...is the reality. At the operational level, there is no conflict between the central agencies and the state police forces.

"They work together, consult each other, share intelligence and, when necessary, mount joint operations to apprehend the suspects. In my view, such silent and invisible work of neutralising terrorist modules deserves as much praise as solving the terrorist cases," he said.

The Home Minister's remarks bear significance as several non-Congress chief ministers including Banerjee, Odisha's Naveen Patnaik, Tamil Nadu's J Jayalalitha, Gujarat's Narendra Modi and Bihar's Nitish Kumar, have opposed the Centre's plan to set up anti-terror hub National Counter Terrorism Centre.

"..I would once again like to underscore my firm belief that, bound by the Constitution of India and working together, we can make this country safe and secure; ensure peace and harmony; and create an environment that will promote faster and more inclusive growth," he said.
