SUVIANA, Italy (AP) — Search and rescue operations have resumed at a hydroelectric plant close to the northern Italian city of Bologna, a day after a devastating blast killed at least three workers, injured five and left four missing. A spokesperson for firefighters says there are very thin hopes of finding someone alive. The massive explosion on Tuesday rocked the plant below the water level, causing flooding and the collapse of part of the nine-story underground structure. Local prosecutors launched an investigation on Wednesday for disaster and manslaughter. Concerns are growing in Italy about workplace safety after a number of accidents.
