Delhi Chief Minister Sheila Dikshit has said that proposed National Counter Terrorism Centre, NCTC will not intrude into the rights of the States. Terming the opposition to the ambitious proposal by a number of non-Congress ruled states as unfortunate, she said the NCTC was being set up to assist the states to deal with security related threats. Rejecting criticism that formation of the anti-terror body would disturb the federal structure, Mrs Dikshit said, the only aim of setting up of NCTC was to confront various threats effectively.AIR correspondent adds that as per the proposal, the NCTC would be a single window organisation that will gather and disseminate intelligence to Central and state security organisations. Functions of NCTC will include drawing up of plans and coordinating all actions and integrating all intelligence pertaining to counter terrorism.
