Bangladesh marks the fifth anniversary of one of the nation's worst industrial disasters on Tuesday, April 24. More than 1,100 workers were killed when the Rana Plaza building that housed a garment factory, collapsed on that day in 2013. The collapse triggered worldwide outrage and spotlighted the Western clothing brands benefitting from the country's low wages, which are among the world's lowest. Five years on, there is growing anger over the slow pace of the court case against those arrested including the owner, Sohel Rana.
