Suspected ethnic militia members hacked to death nine people from a rival tribe and burned down nearly 200 houses as violence continued in India's remote northeast, police said Monday. The raid raised to 17 the number of Karbi tribe members killed since early Saturday, when nearly 150 attackers opened fire on sleeping villagers in Assam state's Bagmari region. Eight died in the attack. A second wave of assaults came Sunday, when nine people were killed and 200 homes torched in a cluster of a dozen hamlets, said D.D. Tripathi, a Bagmari civil administration official. He said the killers wore Indian army uniforms, according to a report of The Associated Press. The attackers' identities were not immediately known, but Tripathi said suspicion fell on Dimasa tribe.
