Arunachal Pradesh, which shares its eastern boundary with the troubled region of Myanmar, and has a large number of insurgents, has become a favourite transit route and operation base for several militant outfits from neighbouring Nagaland and Assam.
Besides the lack of coordination among state police forces of Assam, Nagaland and Arunachal Pradesh, the rugged and thickly forested terrain of the state has made it favourable for insurgents to escape the heat of sustained counter-insurgency operations in Assam and Nagaland.
Security sources said Arunachal Pradesh's eastern districts of Tirap and Changlang bordering Myanmar have become a hotbed of insurgents of late.
The area is infested with factions of the Naga rebels National Socialist Council of Nagaland - Khaplang and National Socialist Council of Nagaland - Isak-Muivah besides anti-talks faction of the National Democratic Front of Bodoland and United Liberation Front of Assam. The NDFB, in fact, has infiltrated the forested area in Arunachal Pradeah bordering North Assam.
The Naga rebel groups are notorious for their extortion operations in Arunachal districts besides engaging in the occasional turf war between them for control over not territory. Arunachal Pradesh does not have sufficient manpower as well as equipment to put up a strong challenge before rebel groups armed to the teeth with sophisticated weapons.
