Agartala, May 21 :     In a massacre reminiscent of the one at Gourangatilla early this year, National Liberation Front of Tripura militants mowed down 19 non-tribals in Bagber village under Khowai subdivision of West Tripura district last evening. Seven more were killed at Ratiya and Chakmaghat under the same subdivision this morning, raising the toll in militant attacks over the past 48 hours to 34. The West Tripura district administration today issued shoot-at-sight orders in Khowai and asked the Army to be on call. Police sources said at least 60 militants, armed to the teeth, raided Bagber at 5 pm yesterday and headed straight for local CPM leader Ajoy Ghosh's house. As the rebels pounded the house with grenades, refugees staying at the adjacent Niranjan Sardarapara School came out of the building and began running towards Kanchanpur. This prompted the militants to open fire and kill three refugees. The militants then trained their guns on villagers who were alerted by the commotion. Sixteen more non-tribals were killed in the indiscriminate firing. The victims were identified as Nabin Debnath, Monica Debnath, Nakul Debnath, Rakhi Debnath, Suklal Nama Das, Premoda Debnath, Nirmala Nama Das, Abala Debnath, Suniti Sarkar, Supriya Debnath, Usha Debnath, Goranga Das, Sikha Debnath, Laxmirani Sarkar, Kumkudini Debnath, Kamalarani Laskar, Birendra Debnath, Dhanibala Debnath and Surendra Debnath. Altogether 16 people were killed in a similar massacre at Gourangatilla in the same subdivision early this year. A source in Khowai said CRPF personnel deployed near the village did not venture out of their camp when the NLFT militants raided Bagber yesterday. 'It was only after Tripura State Rifles jawans reached the village that the militants fled,' he said. The Left Front government also came in for flak from various political parties, organisations and individuals. Expelled CPM leader Nripen Chakraborty said chief minister Manik Sarkar should own moral responsibility for the spate of killings and resign immediately. Chakraborty, one of the few politicians to have refrained from making statements on the situation, broke his silence after yesterday's carnage. 'Manik Sarkar has failed to handle the situation. There is no dearth of leaders in the CPM to replace him,' he said. A senior official, however, said the state government was not to blame for the spurt in killings. He accused security personnel of not doing their job properly, saying, 'Casualties in several militant attacks over the past few months would have been lower had CRPF personnel reacted promptly.' CM's Army plea Prime Minister Atal Behari Vajpayee has promised to consider Tripura chief minister Manik Sarkar's request for deployment of Army battalions in parts of the trouble-torn state. Sarkar, who is here for an inter-state council meeting, said the withdrawal of Army units from the state had emboldened tribal-dominated militant outfits to step up their offensive against non-tribals.
