Bangladesh death toll tops 500

The death toll from last week's building collapse, Banglades's worst industrial accident, rose to 501 on Friday, with the scores of relatives still gathered at the site in a Dhaka suburb clutching photographs of loved ones attesting to the many more still missing.

Police investigating the disaster have arrested Adbur Razzak, an engineer who warned the day before that the eight-storey complex was unsafe. (AP)
