A fire at the dormitory of a seafood company Thursday killed 11 workers and injured 10 others in eastern China, an official said. More than 80 firefighters and 10 fire engines rushed to put out the fire at the dormitory building of a food company in the coastal city of Qingdao, said Jiang Yonglian, a spokesman for the Qingdao city government office. We suspect it may involve electric appliances used to keep warm during cold weather. I do not have any more details about this,'' Jiang said in a telephone interview. It was unclear how many workers were in the building when the fire occurred. Jiang said the injured were being treated at a local hospital.
