Guwahati, Dec 23 (IANS): At least seven people were killed when Bodo militants fired indiscriminately in two villages in Assam Tuesday evening, police said.

The attacks by militants of the National Democratic Front of Bodoland (NDFB) faction opposed to peace talks took place in Saralpara village in Kokrajhar district and Santipur village in Sonitpur district, said Inspector General of Police (Law and Order) S.N. Singh.

Four people were killed in Saralpara, and three in Santipur.

The militants attacked the villages as a response to the intensified operation by the security forces, he said.

The NDFB had Monday triggered a grenade blast in Patgaon in Kokrajhar district, injuring three people.

A joint team of Assam Police commandos and the army had Sunday killed two Bodo militants in neighbouring Chirang district, close to the Bhutan border.

Chief Minister Tarun Gogoi Tuesday said his government will not bow down to any militant threat.
