The deceased, including three women and three children, were allegedly kidnapped by militants before being killed, NDTV reported.
The government suspended internet services for two days in Imphal West, Imphal East, Bishnupur, Thoubal, Kakching, Kangpokpi, and Churachandpur districts to prevent the spread of misinformation and curb unrest, the report said.
The situation escalated as large-scale violence erupted across the Imphal Valley, and mobs targeted the residences of lawmakers.
In one incident, protesters attacked the home of MLA Sapam Nishikant Singh, damaging the gate and bunkers.
Another group stormed the residence of MLA RK Imo in Imphal West’s Sagolband, setting furniture on fire and smashing windows, according to the report.
Protests also erupted in Imphal’s Khwairamband Keithel against the kidnapping and murder of the six victims.
The bodies were discovered near a river in the remote Jirimukh village in Jiribam district, close to the Manipur-Assam border, on Friday evening.
According to sources, the victims had been living in a relief camp and went missing following a gunfight between militants and security forces in Jiribam earlier in the week, the report said.
Meitei organizations have alleged that militants abducted and killed them.
The bodies were transported to the Silchar Medical College Hospital in Assam late Friday night for postmortem examination, police said.
