A devastating fire broke out in a Gandaria residence early Friday after an electrical transformer exploded, leaving three members of the same family critically injured.

The victims—Moslem Uddin (65), his wife Salma Begum (50), and their son Mejbah Uddin (28)—were rushed to the National Institute of Burn and Plastic Surgery.

Dr. Sultan Mahmud Sikder, acting surgeon at the hospital’s emergency unit, confirmed that Moslem suffered 90% burns, Salma 55%, and Mejbah 100%, including severe damage to their airways. Mejbah has since succumbed to his injuries, while the others remain in critical condition.
