At least four people have been killed when a Czech bus plunged down a cliff in the northeast of Austria on Sunday. The tour bus crashed about fifteen kilometres away from crossing the border with the Czech Republic, leaving 38 people injured, some of them in critical condition. Over 100 fire-fighters and rescue teams responded to the scene, where the bus plunged five meters down a cliff after smashing into a tree first. The bus driver told Austrian police that another car cut in front of him, causing him to swerve the wheel, and he lost control of the bus.
