The death toll from a fire at a food and cigarette packaging factory in Bangladesh rose to 29 on Sunday as fire crews began digging through debris, and the number of fatalities could rise with over half a dozen people still missing.
Thick plumes of smoke, pockets of fire and a partially collapsed building stalled search efforts, after a blaze that began early on Saturday swept through a factory making packaging material for local and international companies.
"There are still flames here and there as there are a lot of chemicals in the factory," senior fire service official Masudur Rahman told Reuters.
Saturday's blaze was the country's worst industrial accident since the Rana Plaza building collapse of 2013 that killed 1,135 garment workers, and raises further questions about Bangladesh's safety record.
"We do not know when the search will be completed as it is a huge task," said Ajit Kumar Bhoumik, a senior fire department official. "We need more excavators and trucks to clear debris. We also need more manpower and other resources."
