A BSF jawan was killed and two Assam Rifles personnel suffered gunshot wounds in Serou area of Manipur's Kakching district, the Army said on Tuesday.

The injured have been evacuated by air to Mantripukhri and search operations are in progress, the Army's SpearCorps headquartered in Dimapur said on Twitter.

"Extensive area domination operations by Assam Rifles, BSF & Police undertaken in areas of Sugnu/Serou in #Manipur... Intermittent firing between Security Forces & group of insurgents took place throughout night of 05/06 June. Security Forces effectively retaliated to the fire," it posted on Twitter.

A fierce exchange of fire was also reported between security forces and suspected Kuki militants from Phayeng in Imphal West district, police said, adding that there was no report of any casualty.

Irate villagers had earlier on Sunday night set ablaze an abandoned camp at Sugnu in Manipur's Kakching district on Sunday night, where militants from the United Kuki Liberation Front(UKLF) were staying after signing a peace accord with the government.

The villagers were venting their anger after militants burnt down at least 100 abandoned houses including the residence of Sugnu Congress MLA K Ranjit at Serou in Kakching district on Saturday midnight.

At least 98 people lost their lives and 310 others were injured in the ethnic violence in Manipur that broke out a month ago.

A total of 37,450 people are currently sheltered in 272 relief camps.

Clashes first broke out on May 3 after a 'Tribal Solidarity March' was organised in the hill districts to protest against the Meitei community's demand for Scheduled Tribe (ST) status.

Meiteis account for about 53 per cent of Manipur's population and live mostly in the Imphal Valley. Tribals Nagas and Kukis constitute another 40 per cent of the population and reside in the hill districts.

Around 10,000 Army and Assam Rifles personnel have been deployed in the state to bring back peace.
