Workers bury unidentified garment workers, who died in the collapse of the Rana Plaza building in Savar, during a mass burial in Dhaka May 1, 2013. The European Union is considering trade action against Bangladesh, which has preferential access to EU markets for its garments, in order to pressure Dhaka to improve safety standards after the building collapse killed hundreds of factory workers.
