What's behind India's failure to bring peace in Manipur?

More than a year after deadly ethnic violence broke out between the majority Meitei community and the minority Kuki in India's northeastern state of Manipur, tensions continue to rage.

Peace has remained elusive and — according to many in the state — so has a concrete action from the government.

The latest flare-up of violence occurred on September 1, after months of relative calm. According to authorities, several people have been killed in drone and rocket attacks.

The use of such aerial weapons is a first for the restive state and the government called it a "significant escalation" of violence.

The police in Manipur claim that Kuki groups carried out the drone attacks on Meitei-dominated areas. Kuki organizations, however, refute the allegations, saying that it was the Meiteis who used drones.

Last year was the first time that the Meitei, who are predominantly Hindu, live mostly in and around the state's capital city Imphal, and the Kuki — who are mainly Christian and inhabit the surrounding hills — clashed against each other.

It came on the heels of a demand by the Meitei community to be officially accorded tribal status, which the Kukis protested.

The conflict has since claimed the lives of 225 people, according to official data. More than 60,000 people remain displaced.
