Chumukedima, July 31 (ANI): The issue of illegal taxation, extortion and carrying of arms by cadres dominated the Ceasefire review meeting held between Centre and NSCN (K) at Police Complex in Chumukedima. Chairman of Ceasefire Monitoring Group Major Gen (Retd) N K Singh insisted that NSCN (K) give up extortion activities. He maintained that such actions are against the Ceasefire Ground Rules and also vitiated the peaceful atmosphere. Formed as a splinter group in 1988, NSCN (K) declared ceasefire in April 2001.
