ay, disrupting traffic between the northeast and the rest of India. „The blast damaged the bridge and the vehicles are stranded on the highway,“ an intelligence official told Reuters. The outlawed United Liberation Front of Assam (ULFA) was responsible for a series of blasts in the past 24 hours, the official said. On Saturday, suspected ULFA militants also blew up a stretch of railway track between Bijni and Bongaigaon, some 190 km (118 miles) west of state capital Dispur. Police recovered an unexploded bomb near the site of the blast. „The recent violence by ULFA is aimed to disturb the Independence Day celebration (on August 15),“ the intelligence official said. Press Trust of India said other bombs exploded in the town of Sarupeta in Barpeta district late on Saturday, damaging transmission towers of the state-run Power Grid Corporation. There were no casualties, the news agency said. ULFA has been fighting for self-rule Assam since 1979. It accuses the federal government of exploiting the state‘s mineral resources and ignoring the local economy.
