Kohima, Nov. 30 :     Nagaland Governor Om Prakash Sharma today said the security forces would be forced to resume their offensive against militants in the state if violence continued unabated. In a message on the eve of ?Statehood Day?, the Governor said the ceasefire between the Centre and the National Socialist Council of Nagalim (Isak-Muivah) had been a one-sided affair so far. ?Only the security forces exercised restraint and the euphoria over the declaration of a truce did not last long,? he said. Sharma termed the attempt on chief minister S.C. Jamir?s life yesterday ?a cowardly act?. He said the attack was a setback for the peace talks between the Centre and the NSCN(I-M). ?It will be naive to presume that the restraint shown by the security forces will last forever. It is quite clear that subversive elements are determined to leave no option for the security forces but to retaliate,? the Governor said. Accusing the underground Naga rebels of using the ceasefire as a ?license for self-aggrandisement?, Sharma said they had crossed ?all limits of acceptable behaviour?. He said the attitude of the rebels was in stark contrast to the valour shown by Naga soldiers during the Kargil conflict. The NSCN(I-M) denied being involved in yesterday?s ambush, but state home minister N. Rio said there was ?enough evidence? to establish its involvement. Rio said the ceasefire between the Centre and the NSCN(I-M) could be abrogated if the banned outfit continued to violate the ?ground rules? of the ceasefire. However, NSCN(I-M) information and publicity secretary Ng. Hungshi said the question of attempting to kill the chief minister while peace talks were underway did not arise. He said the attack could be the handiwork of forces bent on disrupting the peace process in Nagaland. Several organisations, including the Nagaland Peace Centre, the Ao Senden and the Angami Public Organisation, have condemned the attempt on Jamir?s life. Compensation: The Nagaland government today announced ex gratia of Rs 2 lakh each for the next of kin of the two constables who were killed in the ambush on the chief minister?s convoy yesterday. The bodies of the two constables, Khenga Rengma and Limasunup Ao, were brought to the Phoolbari area here so that people could offer floral tributes. More forces Stunned by yesterday?s attempt on the life of Nagaland chief minister S.C. Jamir, the Centre today decided to deploy more security forces in the state, reports our correspondent from Delhi. The decision was taken at a high-level meeting of senior officials of the Union home and defence ministries and representatives of the security forces operating in Nagaland where a ceasefire between the Centre and the National Socialist Council of Nagalim (Isak-Muivah) has been in operation since July 1997. A home ministry statement said the meeting discussed the situation arising out of the ambush on Jamir?s convoy. Following detailed discussions and consideration of relevant facts, it was decided that the strength of the security forces would be increased. Denying that the ceasefire was in jeopardy, a home ministry spokesman said the ground rules of the ceasefire, drawn up between the Centre and the NSCN(I-M), would be implemented with ?greater vigour.? The security forces have been instructed to ?come down heavily? on all violations of the ground rules, he added. One of the 11 ground rules finalised between former Union home secretary K. Padmanabhaiah and NSCN(I-M) representative V.S. Atem in October 1997, says neither the Indian Army, the paramilitary forces and the police nor the NSCN(I-M) should carry out offensive operations like an ambush, raids and attacks leading to death, injury, damage or loss of property against each other. Preliminary investigations being conducted by the state police hint at the involvement of the NSCN(I-M). An official said the outfit has a training camp barely three km from Pherima, between Dimapur and Kohima, where 14 improvised explosive devices (IEDs) were detonated when the chief minister?s seven-vehicle convoy was passing early yesterday morning. The home ministry reiterated that the Centre was committed to peaceful dialogue as a means of settlement of disputes and was willing to talk to all underground outfits. ?However, violence will not be tolerated and, accordingly, security forces in the areas affected by insurgency are being geared up to ensure that they are in a position to tackle any eventuality,? the statement said.
