A common definition of terrorism is the systematic use or threatened use of violence to intimidate a population or government for political, religious, or ideological goals. Terrorism in India, according to the Home Ministry, poses a significant threat to the people of India. Terrorism found in India includes ethno-nationalist terrorism, religious terrorism, left wing terrorism and narco terrorism.
The regions with long term terrorist activities have been Jammu and Kashmir, east-central and south-central India (Naxalism) and the Seven Sister States. In August 2008, National Security Advisor M K Narayanan has said that there are as many as 800 terrorist cells operating in the country. As of 2013, 205 of the country’s 608 districts were affected by terrorist activity. Terror attacks caused 231 civilian deaths in 2012 in India, compared to 11,098 terror-caused deaths worldwide, according to the State Department of the United States; or about 2% of global terror fatalities while it accounts for 17.5% of global population.
Media reports have alleged and implicated terrorism in India to be sponsored by Pakistan, particularly through its Inter-Services Intelligence (ISI). In 2012, the US accused Pakistan of enabling and ignoring anti-India terrorist cells working on its soil; however, Pakistan has denied its involvement.
