Even after 24 hours, the fire at the garment factory and chemical warehouse in Mirpur’s Shialbari area has not been fully put out.
On Wednesday morning, smoke was still seen coming from the warehouse.
Fire service teams, along with chemical experts, are still working at the scene.
Officials said it will take more time to control the fire because of the chemicals inside.
Several people fell sick from toxic smoke, prompting authorities to close nearby roads and evacuate residents using loudspeakers.
Firefighters are working with extreme caution, while many people are still gathered at the site searching for missing relatives.
