Normal life has been disrupted in several northern districts of Assam and neighbouring Arunachal Pradesh following a 24-hour economic blockade call by the pro-talk group of the banned National Democratic Front of Bodoland NDFB. The blockade on the National Highway number 52 since five this morning has been called demanding Centre’s immediate response towards holding peace talks with the outfit. The militant outfit has already announced unilateral ceasefire and most of their cadres were taking shelter in designated camps.Reports reaching Guwahati said the blockade supporters damaged an Assam State Transport Corporation bus at Rowta in Darrang district this morning. The driver of the bus is reported to have injured seriously when the miscreants resorted to stone pelting. No vehicle plied and the highway looked deserted. The National Highway plays an important role for transporting man, materials and essential items in the northern parts of Assam and higher reaches of Arunachal Pradesh, bordering China and Bhutan.
