The death toll in Bangladesh's worst industrial disaster today approached the 900 mark as rescuers overnight pulled out 80 more bodies from sandwiched floors of the ill-fated eight-storey building that collapsed last month.

"The death toll now stands at 892," an official said as the military-led salvage operation entered the 16th day today. Hundreds of bodies are still trapped under the debris of the illegally constructed Rana Plaza building as many have remained missing, local media reported.

The building in Savar near the capital Dhaka that housed five garment factories collapsed on April 24. It is still unclear how many people were there on that fateful day.
