Two people were killed after a driver rammed his car into the crowd in Germany's Leipzig city on Monday, according to authorities.
An additional three people were seriously injured in what officials believe was a deliberate rampage, Mayor Burkhard Jung said.
He described it as "a terrible tragedy." An unspecified number of people sustained less serious injuries.
The driver, a 33-year-old German citizen, was detained in the car. Police said he was a German-born resident of the Leipzig area.
Prosecutors said he is under investigation on suspicion of murder and attempted murder. There was no immediate word on a possible motive.
