A massive fire has swept through an inland container depot in southeastern Bangladesh, killing at least 49 people and injuring more than 300, officials said on Sunday, the latest incident highlighting the country’s poor industrial safety track record. The fire broke out at a container facility on Saturday night at Sitakunda, 40km (25 miles) from the port city of Chittagong, triggering a huge blast and multiple container explosions subsequently at the site, officials said.
