<br/>The Centre has said anti-Naxal operations will continue till the extremists agree to talks. It has convened a meeting of Chief Ministers of four Naxal affected states in Kolkata next month to fine tune the joint operations. A Home Ministry spokesperson said the meeting will be attended by Chief Ministers of Jharkhand, Orissa, West Bengal and Bihar. Union Home Minister P Chidambaram had earlier held a meeting with Jharkhand Chief Minister Shibu Soren in New Delhi and later said anti-Naxal operations will stop only if the left-wing extremists abjure violence and decide to come to the negotiation table.<br/>
