On 18 December, curfew was imposed in certain parts of Imphal East district of Manipur in the wake of continued violence in the region following Friday's triple blasts.
The curfew comes into force from Sunday noon and covers Porompat and Sawombung subdivisions of Imphal East district and will continue till further directions, an order issued by the district magistrate said.
The government's decision to clamp the curfew follows the shutting down of mobile internet services in Imphal West district to halt spreading of rumours through social networking sites.
The landlocked state has been experiencing severe hardship in supply of essential items since November 1 after United Naga Council (UNC) imposed an indefinite economic blockade on the two national highways that serve as lifeline for the state.
The blockade was imposed following the state government's announcement of formation of seven new districts, four of which have been formally inaugurated.
Tension in the state heightened after suspected militants continued their violent attacks on Manipur Police and other state forces in the last few days that left three policemen dead and 14 others injured last Thursday.
The attack was followed by triple bomb blasts at Nagaram area in Imphal West district allegedly by Manipur Naga People's Front on Friday.
In another incident, suspected militants overpowered a small outpost of Indian Reserve Battalion (IRB) at Nungkao area on Saturday in Tamenglong district and fled with nine service weapons.
