At least 12 people were killed and as many as 300 injured when a powerful explosion triggered by a gas pipeline leak ripped through a plastic and chemicals factory in eastern China. State-run agency Xinhua reported that the blast occurred at an abandoned plastic and chemicals factory and an initial investigation showed gas leak from a pipeline going through the plant as the trigger of the explosion. Buildings and vehicles within a 100-meter radius around the factory were seriously damaged. The impact of the explosion also damaged a bus that was passing the area, injuring many passengers. Media reports said a man was hit by a falling ceiling when he was sleeping at home. He died later in hospital.
