An indefinite curfew has been imposed from 5 pm in the Tinsukia sub-division on Saturday in the wake of ULFA attacks on non-Assamese people.
Forty-five persons have been killed since Friday in the attacks in Tinsukia and Dibrugarh districts.
The order to impose the indefinite curfew was issued by Tinsukia district deputy commissioner Afsar Hazarika.
Targeting migrant non-Assamese people, the ULFA gunned down 26 milkmen and brick kiln workers early this morning, while another 19 persons were shot dead and 17 others injured last evening in two attacks in Tinsukia and Dibrugarh districts.
The militants swooped on remote village Ghuramora, under Sadiya police station of Tinsukia district, early today and fired from their sophisticated weapons on the brick kiln workers and milkmen killing 16 on the spot and wounding five others, official sources said.
At Charaipung forest village, under Pengeree police station in the same district, the guerrillas killed another four pesons.
