The Army has been employed in the NE to fight insurgency. In Nagaland after protracted negotiation there is a ceasefire with both the main groups that is NSCN(K) and NSCN (IM). However, inter factional clashes continue between the groups. In Manipur, the hill districts of Ukhrul, Senapati and Tamenglong are Naga dominated and have a natural affinity to Nagaland. The Army after its deployment in Apr 2004 has been able to clear large areas of Manipur of terrorist influence. However, Imphal district where AFSPA has been lifted provides a safe haven for terrorist activities. In Assam ULFA continues to be the main insurgent group. However, their support base is severely eroded and activities are on a low key due to own operations.
