Why peace is fragile between two India statesMizoram officials alleged that 200 policemen from Assam, led by a senior officer, overran one of their police outposts at the border town of Vairengte. The evicted policemen, barely 20 of them, were joined by reinforcements, according to locals - and they retaliated after taking position in the hills overlooking the camp.Local Mizos also burnt down buses that had carried the Assam policemen to the border and clashed with villagers from Assam backing up their force. For a while, it was like a war between two countries," said Pu Gilbert, a villager in Vairengte.The regional Mizo National Front (MNF) rules Mizoram and is part of Northeast Democratic Alliance led by India's governing Bharatiya Janata Party.
