The government has ordered an investigation into the cause of the fire.

At least 52 people were killed and several others injured in a massive fire that broke out at a six-storey juice factory in Bangladesh’s Narayanganj, officials said on Friday.

Eighteen firefighting units from Narayanganj and Dhaka are at the scene to douse the fire at the Hashem Food and Beverage factory.

Eighteen firefighting units were struggling to douse the fire at the factory building of Hashem Foods Limited.

The factory caught fire around 5:30 pm on Thursday. Although the blaze was almost under control early Friday, flames broke out again on the fifth and sixth floors of the building.

Several workers jumped off the building to escape the devastating fire, according to firefighters. Three of them succumbed to their injuries on Thursday.

People gathered in front of the building in search of their loved ones who are still missing. Of the many missing, the identities of 44 missing workers have been confirmed, the Dhaka Tribune reported.

Relatives of the missing workers have alleged that the front gate and only exit of the factory remained locked at the time of the fire. They also claimed that the building had no proper fire safety measures in place.
