At least 435 houses were gutted in a fire at Nayapara Registered Rohingya Camp in Teknaf upazila of Cox’s Bazar district early Thursday.   Abdul Hannan, in-charge of the camp, said the fire broke out at a house in the camp under E-block around 3 am and spread soon.   The fire spread fast as most of the residents use gas cylinders in the camp for cooking, he said.
