At least 25 factory workers have been killed in a huge fire near Bangladesh's capital on Saturday, after a boiler exploded at a packaging factory.
Officials say the death toll is expected to go up as rescue efforts continue.
The cause of the explosion is unknown.
The fire broke out while employees were inside the facility in Gazipur district just north of Dhaka, local police chief Harunur Rashid said.
Fire officials working at the scene said that the explosion was huge and that the fire triggered by the blast spread quickly because flammable chemicals were stored at the factory.
At least 50 people are hospitalized for their injuries.
Saturday was the last working day at the factory before the workers were to go on leave for a weeklong holiday for the Islamic festival of Eid al-Adha, which falls on Tuesday.
Authorities have ordered an investigation.
Factory safety is a major concern in Bangladesh, which has thousands of garments from global clothing chains like Wal-Mart and H&M.
In 2013, a commercial complex near Dhaka housing five garment factories collapsed, killing 1,135 people, Bangladesh's worst industrial disaster.
