In Bangladesh, at least 100 people have been killed and dozens other injured in a major fire yesterday in Nimtoli locality of old Dhaka area. It began after an electrical transformer exploded, engulfing housing blocks and shops in flames. Firefighters say they have now got the blaze under control in the old district of Nimtoli.<br/><br/>Nimtoli district is crammed with buildings and roads are narrow, making access for the emergency services difficult. The BBC correspondent says the city is one of the most densely populated cities in the world and Nimtoli is its most crowded district. <br/><br/>He says many people live in badly constructed multi-storey buildings with no fire escapes or safety equipment. Fire department chief Abu Nayeem said the fire had engulfed at least seven buildings. <br/><br/>He told newsmen that there were shops selling chemicals on the ground floor, which were caught by the fire as it spread very quickly. The temperature and fumes became unbearable because of the chemicals. <br/><br/>He said ‘we struggled to get inside due to the narrow stairways of the very old buildings." Imrul Hasan, a doctor at the burns unit of Dhaka Medical College Hospital told newsmen that most of the dead had minimal burns and the cause of death for most appeared to have been smoke inhalation. <br/><br/>The number of dead is rising every moment, he said. Dr Hasan said the burns unit at DMCH had already been overcrowded with patients before the blaze. <br/>
