Three people were killed and five others seriously injured after a tower crane fell from a building under construction in south China"s Guangdong Province Friday afternoon, Xinhua quoted local authorities as saying today. The accident happened at about 4:10 p.m. when the 30-tonne tower crane fell from the 50th floor of Taishang Building in Dongguan city. The crane broke through three stories in the basement and finally landed, a municipal government spokesman said. Three workers were killed at the scene and the injured were receiving treatment at a local hospital. Initial investigation suggests "quality problem" of the tower crane caused the accident, the spokesman said. The Taishang Building, dubbed as "NO.1 Skyscraper in Dongguan," is expected to be 289 meters tall, with 68 floors on the ground and four stories in the basement. About 50 stories have been completed when the crane fall took place. --SPA
