Bodies. More bodies. More horror.

The toll climbs:

The death toll in the Rana Plaza disaster soared to 517 on Friday, as rescue crews spent a 10th day digging through the rubble and investigators continued to interrogate the building’s owner and others arrested in the case.

The collapse of the Rana Plaza building, which housed five clothing factories, is the deadliest disaster in the history of the garment industry, with the death toll likely to keep rising as work crews now use heavy machinery to clear debris from some of the most devastated sections of the building.

Thousands of onlookers visit the wreckage daily, including some bearing small posters with photographs of loved ones still unaccounted for. On Friday, Mohiuddin Khan Alamgir, Bangladesh’s home minister, said more arrests were possible in coming days.

“This is a case of sheer negligence and sheer arrogance,” Mr. Alamgir said in an interview. “Arrogance on the part of the owner and negligence by the engineers and the local government authorities.”
