A 9-month-old baby was among five people killed Tuesday when a inebriated man suspected of suffering psychiatric problems drove his vehicle nearly a kilometer (0.6mi) down a pedestrian shopping street in the southwestern city of Trier, German authorities said.

"I think this is Trier's darkest day since World War II," Mayor Wolfram Leibe said during a press conference. "It's a horror scene."

The driver, identified only as a 51-year-old German national and resident of the metropolitan area, steered his Land Rover onto the pedestrian mall in the city center around 1.50 pm and witnesses said that he appeared to be trying to hit people.
