A tribal feud in India's remote northeast has left at least 37 people dead.
Reports from the state of Assam say tribal militants from the Dimasa tribe ambushed a bus east of the capital, Guwahati, and used machetes to kill 22 people from a rival ethnic group. Hours later, they set fire to some 80 homes in two villages, killing 15 people.
Police said all those killed belonged to the Karbi tribe.
Fighting earlier this month between the two tribes killed at least 33 people and forced hundreds of people to flee their homes.
The Dimasa and Karbi tribes have been fighting for years over land in Assam. The state is home to a large number of tribal and ethnic groups, some of whom are battling the Indian government for self-rule in the region.
