Rescuers continue today to search for 16 workers missing at the site of a collapsed subway tunnel in eastern China, reports the Xinhua news agency. At least five people were killed when the construction site caved in Saturday on a Hangzhou roadway, swallowing a bus and 11 other vehicles. "There's slim chance for the trapped workers to survive, because of heavy flooding," said an official. Close to 50 people were rescued shortly after the collapse. (More subway stories.)
