At least 48 students fell ill after a fire broke out at a madrasa in Narayanganj's Fatullah on Monday night, triggering heavy smoke that spread through the building.
Three of the students are in critical condition and receiving treatment in the intensive care unit (ICU).
The incident occurred at Jamia Ashrafia Madrasa in the Fatullah area.
Dr Sultan Mahmud Sikder, a resident physician at the emergency department of the National Institute of Burn and Plastic Surgery, confirmed the incident, saying the fire reportedly originated from an electrical short circuit in one section of the madrasa.
The building was quickly engulfed in smoke, triggering panic among students inside. As they scrambled to escape, some were trapped in the smoke-filled premises, suffering respiratory injuries and breathing difficulties.
A total of 48 students were rescued and rushed to the National Institute of Burn and Plastic Surgery for emergency treatment.
Three students -- Yousuf, 18, Khairul, 22, and Zubair -- are in critical condition and currently receiving treatment in the ICU.
Specialist doctors and healthcare workers are keeping all the injured students under round-the-clock medical observation, Dr Sikder said.
