Guwahati:Two Bihari businessmen were shot dead by ULFA insurgents at a remote village in Assam's Tinsukia district this evening, in a chilling reminder of the massacre by the banned outfit of 70 people, mostly Hindi-speaking migrants, earlier this month.

The ULFA cadres went to Chapakhowathe village under Panchsmile outpost of Sadiya outpost at 6:00 pm and shot dead 65-year-old Sambhu Prasad and 45-year-old Sriprasad Bairagi, sources said.

Eyewitnesses said the militants fired six to eight rounds killing the two on the spot.

Seventy people, mostly Bihari migrants, were killed by ULFA between January five and eight in different districts.

Meanwhile, a crude bomb exploded near a BSNL tower at Duponigaon in Sibsagar district this evening.

Additional Superintendent of Police Deepak Chowdhury said the army and the police checked the area and found a crater near the boundary wall of the tower.

"Telephone services were not disrupted," he said.
