Local police reported that Assam's Chirang district, subject to increasing unrest, on Wednesday was again assaulted by suspected militants.
Unidentified militants threw grenades in an attack on the Bodo Basugaon area in Chirag near the region's railway tracks, an area 100 miles from Assam's main city Guwahati, one of the country's four Bodoland Territorial Areas Districts.
Chirang district police said two grenades were thrown. One, however, one of them failed to explode and was recovered from the site. They said the investigation was focusing in determining which militant outfit was involved in the blast.
Parda Phas news agency reported that Chirang was one of the three districts hit by recent clashes between the Bodos and Bengali-speaking Muslim settlers.
Bodoland's city of Kokrajhar three months ago was the scene of a wave of ethnic clashes in which more than 80 people were killed.
