The NSCN-Reformation, one of the strongest armed groups in Nagaland, will observe Monday as a black day to protest against a year of abrogation of ceasefire by the NSCN-Khaplang group.
"March 28 is a black day for us as instead of considering peace, the Khaplang group last year abrogated the ceasefire with the Indian government," Wangtin Konyak, president of NSCN-R, told IANS.
The NSCN-R came into existence in April 2015, immediately after the NSCN-Khaplang broke the ceasefire with New Delhi.
The founders of the NSCN-Reformation, who were formerly senior leaders of the Khaplang group and opposed to abrogating the peace pact, now have a ceasefire with the Indian government.
The group was the first among other armed groups of Nagaland to publicly support the framework agreement inked between the NSCN-IM and the central government on August 3, 2015.
The abrogation of the ceasefire by the Khaplang group was followed by a series of attacks on the Indian army, including the killing of four Assam Rifles personnel in Mon district of Nagaland and the later killing of 20 Dogra Regiment soldiers in Chandel district of Manipur.
