The Centre on Friday slammed Orissa government for the 'failure' to contain the 'regrettable and condemnable' Kandhamal violence for over a month since it erupted in August last year.
"What happened on August 23 and thereafter was regrettable and condemnable. Moreover, it was the failure of the police for 30 to 40 days," Home Minister P Chidambaram told reporters after meeting Chief Minister Naveen Patnaik.
Chidambaram, who is on a two-day visit to the state, said the situation in the riot-torn district was returning to normal.
"Now the situation is returning to normal but we cannot lower our guards," he said.
About increasing activities of Naxals in the state, Chidambaram said, "our response to Left wing extremism is that there is no room for violence.
"The CPI-Maoist was and is a terrorist organisation and we will not yield any ground to CPI-Maoist. We will resolutely oppose and ensure that all violence ends".
The home minister said he has assured the chief minister of all help to tackle Maoists in the state.
"I have assured Chief Minister Naveen Patnaik of all help. A plan has been drawn up to handle Left wing extremism," he said.
