Clashes between rival ethnic groups in India's remote northeast have killed 11 people, police said Sunday, as they imposed a strict curfew in the area and issued shoot to kill orders. Militants from Manipur state's majority Meiti tribe killed six members of the minority Kuki tribe in a gunbattle late Saturday in the town of Moreh, sparking a retaliatory attack by armed Kuki that killed five ethnic Meiti construction workers, according to a statement from the police control room in Imphal, the capital of Manipur. Police said a curfew has been imposed and that they have been ordered to shoot anyone violating it, the Associated Press reported.
