Unicef has mourned the children who were killed in a recent factory fire in Narayanganj's Rupganj. "We offer our deepest sympathies to the families of those who died, were injured, or remain unaccounted for," said Unicef Representative in Bangladesh Tomoo Hozumi Sunday. With over 50 casualties reported, as many as 16 or more of these may be children, Unicef said.

"This tragic incident brings to light yet again that despite laws that should protect them, many children in Bangladesh are not only working, but they are working in hazardous conditions, he added. According to the Bangladesh Multiple Indicator Cluster Survey 2019, over 4 million children are working, and more than 3 million of these children are trapped in the worst forms of child labour that involve hazardous working conditions.

At least 52 people died in a fire Thursday at a factory in Narayanganj's Rupganj, the latest industrial disaster in the country. The International Trade Union Confederation Bangladesh Council Saturday called for making the results of the Department of Inspection for Factories and Establishments' work on anomalies of the factory – especially the recruitment of child workers – public.
