BEIJING (AFP) - Seven workers were killed and three others injured when a bridge under construction in eastern China collapsed, state media reported Saturday. The accident occurred in the city of Nanjing when part of the steel structure gave way, plunging the workers more than 10 metres (30 feet) to their deaths. The three other workers were at a lower level and did not receive life-threatening injuries. China has a notoriously poor record of workplace accidents, blamed on widespread disregard for basic safety measures as companies chase profits.
