Two suspected rioters were killed and at least five injured in an exchange of fire with security personnel in Kangpokpi district in Manipur on Thursday morning, officials said.

They said armed rioters opened unprovoked firing at Haraothel village. The army said security forces personnel “responded in a calibrated manner” to tackle the situation.

Another rioter was also believed to have been killed, but the body is yet to be retrieved as the spot witnessed intermittent firing, they said.

Later in the day, members of the community to which the two rioters belonged collected their bodies and took out a procession to Manipur chief minister Biren N Singh’s residence here, the officials said.

The demonstrators, led by women, even dared police to arrest them. They were also seen burning tyres in the middle of the road to prevent police movement.

As police stopped them from marching to Singh’s residence, the processionists turned violent, they said, adding police used tear gas shells and resorted to lathi-charge to disperse the mob.

Officials said extra policemen were deployed in the city as a precautionary measure.

Earlier in the day, Assam Rifles columns were deployed at National Sports University and K Munlai village after intermittent gunfire from automatic weapons was heard from multiple directions towards Haraothel village.

An official said unidentified gunmen fired without provocation in the wee hours of Thursday and again in the evening.

Giving details of the morning firing, the official Twitter handle of the army, operating in the region, stated armed rioters opened unprovoked firing at 5.30 am.

“Own troops deployed in the area immediately mobilised to prevent escalation of situation. While enroute to the site, own columns drew effective fire from armed rioters,” the official “Spear Corps” handle of the army said.
