Para military troops stand guard at the Tongi railway station, 30 km (19 miles) from the capital Dhaka, December 4, 2006, on the 2nd day of the fourth nationwide transport blockade in as many weeks called by the 14 party alliance. Witnesses said road links between the capital Dhaka and the port city of Chittagong, as well as other main cities, were paralysed as the blockade took hold early on Sunday, a working day in mainly Muslim Bangladesh.
