Over two dozen organisations in Assam staged an indefinite blockade on a national highway on Monday as part of campaigns to prevent the National Hydroelectric Power Corporation (NHPC) from constructing a dam and a 2,000-MW project in adjoining Arunachal Pradesh.

The protest is being spearheaded by two apex anti-dam groups – the All Assam Students' Union (AASU) and the Krishak Mukti Samaj Samity (KMSS) – which are holding demonstrations along NH 52 and preventing trucks from carrying machineries and equipment to the NHPC project site in Arunachal Pradesh.
