Seven districts in Delhi have come "under the influence" of Maoists while 84 districts across the country witnessed violent activities of Naxal rebels.

Minister of State for Home Jitendra Singh said the districts in the national capital which have come under the influence of Left wing extremism are Central Delhi, New Delhi, South Delhi, North West Delhi, South West Delhi, North and North East.

There are nine districts in Delhi.

"In 2011, a total of 84 districts in India witnessed violent activities of some nature by LWE outfits, an overwhelming majority of which were by the CPI(Maoist). Out of the above, around 50 districts witnessed moderate to high levels of violence," Singh told Rajya Sabha today in a written question.

He said the districts which are classified as "under LWE influence" was based on overground activity of the front organisations of the CPI(Maoist) and other Left wing extremist groups.

"The total number of such districts in the country in 2011 was 203 (including the 84 violence affected districts)," he said.

Singh said since 2009, significant spatial reduction in Left wing violence has been noticed in Andhra Pradesh, Uttar Pradesh, Bihar and Madhya Pradesh.

West Bengal's West Midnapore district, which had witnessed 360 killings between 2009-11, has not seen any violence till July 31 this year.

Similarly, Chhattisgarh's Dantewada, where 280 people were killed in Maoist violence in previous three years, has witnessed 13 deaths in the first seven months of 2012.
