At least five workers, including one woman, were killed and many more injured at a devastating garment factory fire in a mega industrial belt in Bangladesh's Ashulia on the outskirts of capital Dhaka Tuesday afternoon, an official said. Azizur Rahamn, doctor of a hospital in Ashulia, told Xinhua over phone that 'there are five bodies of the workers in the hospital.' 'We've treated at least 20 workers and sent them to burn unit of Dhaka Medical College Hospital for better treatment,' he said. He further said, 'Whom we've treated five are very critically injured.' Nazmul Huda, local correspondent of a private TV channel ETV, said, 'I've seen total eight bodies, five in the hospital and three on the spot.' An official of the factory on condition of anonymity said there were around 5,000 workers in the 10-Storey building ready-made garment factory, but fortunately most of them were outside for lunch while fire broke out at the 9th floor at around 1 p.m. local time. The cause of the fire is still unknown.
