One person was shot dead and houses were set on fire as fresh ethnic violence erupted in India's Northeastern State Of Manipur.

Officials said the violence was sparked among the Kuki Tribal Group of the Majority Meitei Community being given guaranteed quotas of government jobs and other perks in a form of affirmative action.

An indefinite curfew was reimposed on Wednesday in the flashpoint Bishnupur District after suspected militants fired at a group of people, fatally wounding one person.

Manipur has been on the boil after an explosion of inter-ethnic violence this month killed at least 70 people and left tens of thousands displaced. Some 2,000 houses were also burned down across the state.
