Imphal January 30 (IANS): Manipur is bracing for a protracted economic blockade during which people may be deprived of consumer and other items. Two tribal students' organisations -- the Kuki Students' Organisation (KSO) and the All Naga Students' Association Manipur (ANSAM) -- in a joint statement issued on Friday night announced a blockade would be imposed from February 1 midnight. The blockade will cover National Highway 2 from Dimapur in Nagaland to border town Moreh, National Highway 37 from Jiribam bordering Assam to Imphal and National Highway 150 Jessami (Manipur) to Mizoram. Trucks and other vehicles carrying goods will not be allowed to ply, Seiboi Haokip of the KSO and A.C. Thotsho of the ANSAM said as they sought regularisation of contractual teachers. "The contractual teachers should be regularised for ensuring quality education in the hill districts." These teachers were engaged from 2006. During a screening, 772 teachers were found eligible for regularisation. However, the government has not done anything to regularise their services so far.
