At least three people have died and dozens injured after a man drove his car into crowds in a square in the Austrian city of Graz.
The square where the incident occurred was hosting an event related to the Austrian Formula 1 Grand Prix, which is being held nearby.
The driver has been arrested, though police say there were no indications the attack was motivated by terrorism.
"The driver deliberately drove into pedestrians. I myself saw a woman being run over," Siegfried Nagl, the city's mayor, told Kleine Zeitung newspaper.
Sixty ambulances and four helicopters, many of which were stationed at the Spielberg track, were sent to the scene.
