Seventeen people including 10 firefighters fell sick due to huge black smoke while trying to douse the New Super Market fire.
All of them are giving treatment at emergency department of Dhaka Medical College Hospital.
Of the injured, one is volunteer, one is shop owner and five are employees.
Though it has passed five hours, the fire is still burning.
