The Army on Monday gunned down two members of the banned United Liberation Front of Assom in an encounter inside the Ranglu Forest area in Arunachal Pradesh.

Troops of the 11 Sikh Light Regiment gunned down senior ULFA cadres Nitul Sonowal and Muleswar Sonowal after a fierce gun battle, said sources.

The Army also recovered an US made carbine from the possession of the slain militants. While Nitul is from Assam's Dibrugarh district, Muleswar is from Tinsukia district.

In a separate incident, 11 people were injured in a bomb blast at a fair in Dhansirimukh in Udalguri district of north Assam on Monday afternoon.

According to the police, the fair is an annual event held after Lakshmi Puja celebrations every year. The injured were rushed to the nearest government-run hospital at Mangaldoi. The police have launched a combing operation in the area to nab the perpetrators of the blast.

The police are yet to ascertain which militant group was involved in the blast. The area is believed to be a stronghold of the banned National Democratic Front of Bodoland which is currently in a state of truce with the government.
