Suspected terrorists belonging to the National Socialist Council of Nagaland - Isak-Muivah (NSCN-IM) fraction shot down a teacher at Aimol village in Manipur's Chandel district on Monday.
According to initial reports, the terrorists resorted to heavy firing post the incident. The situation is said to be tense in the area.
The government had on September 16 last year declared the NSCN-K, responsible for explosions, ambushes and bombings, as an unlawful organisation for a period of five years.
The NSCN was formed on January 31, 1980, by Isak Chisi Swu, Thuingaleng Muivah and S.S. Khaplang opposing the 'Shillong Accord' signed by the then NNC (Naga National Council) with the Indian Government.
Later, differences surfaced within the outfit over the issue of commencing a dialogue process with the Indian Government and on April 30, 1988, the NSCN split into two factions, namely the NSCN-K led by S. S. Khaplang, and the NSCN-IM, led by Isak Chisi Swu and Thuingaleng Muivah.
