NEW DELHI: Gun battles between rival ethnic groups in India’s troubled northeastern Manipur state killed three men, police said, the latest unrest in the far-flung region. Manipur has seen periodic clashes for nearly three years between the predominantly Hindu Meitei majority and the mainly Christian Kuki community in which more than 250 people have been killed. “In a heavy exchange of fire … three individuals sustained fatal bullet injuries,” Manipur police said in a statement late Friday.
