A vehicle plowed into a busy sidewalk in Melbourne on Thursday, injuring at least 14 people, authorities said. The driver and another man have been arrested.
Police said it was a "deliberate act."
Commander Russell Barrett, of Victoria Police, told a news conference that several of the injured were in critical condition. He said the motive for the attack wasn't yet known.
The vehicle hit a number of people in front of Flinders Street Station in the center of the Australian city just after 4:30 p.m. local time.
Sky News Australia reported the driver of the white Suzuki SUV was wrestled to the ground and handcuffed after his vehicle crashed into a bollard by a cable car stop.
Witnesses told Sky News the car ran a red light, accelerated and hit the pedestrians, in an area with a 25 mph speed limit.
"A number of people were treated at the scene for a range of injuries and have been transported to hospital." Victoria Police said in a statement.
