The town is under siege because of the threat of a blockade, led by the All Barak Youth Students Association, demanding entry into the town without the inner-line permit (ILP), a legal requirement.
Deputy commissioners of Cachar and Kolosib districts are scheduled to meet on Friday to discuss the issue.
An NGO, Coordination Committee, and the Mizo Zirlai Pawl held a public meeting in the town yesterday to take stock after Saturday's incident of border incursion, allegedly by an Assam minister.
They resolved to demand strict implementation of the ILP and resist all attempts to dilute it. They said the SDO (civil) should be empowered to issue ILPs for six months at Vairengte, hold talks with the Assam government and ensure the current situation does not escalate into a communal conflict.
