In Manipur, vehicular traffic along the three National Highways-39, 53 and 150 has been hampered badly due to the ongoing economic blockade called by the Sadar Hills District Demand Committee, SHDDC, from the first of this month and the indefinite bandh along the three National Highways by the United Naga Council, UNC, from today. While the SHDDC is demanding a full-fledged Sadar Hills District to be carved out from Senapati District, the UNC is demanding that no attempt should be made to bifurcate Naga areas in Manipur to create new districts.
