The Indian government deployed military helicopters Thursday to track down tribal fighters in the northeastern state of Assam after insurgents killed 75 people this week.
An additional 5,000 military officers arrived in Assam in response to this week's attacks, the government reported.
Suspected fighters of a faction of the National Democratic Front of Bodoland (NDFB) attacked four villages in the space of an hour Tuesday, pulling people out of their homes and shooting them dead. The NDFB is an armed separatist group for the ethnic Bodo people, which has accused New Delhi of squandering their state's resources and flooding the area with outsiders.
“The violence is not merely a case of insurgency but one of terrorism. We are going to deal with this sternly,” Indian Home Minister Rajnath Singh told reporters.
Singh went on to note that the central government "will adopt a zero tolerance policy" towards terrorism and declared that "there would be no talks at any cost" with such militant outfits.
According to IHS Jane's Terrorism and Insurgency Center (JTIC), 195 attacks were attributed to the different NDFB factions between January 1, 2013, and May 26, 2014, which is an average of more than two attacks per week.
