One person was killed and two injured Saturday when a man rammed a vehicle into pedestrians in the southern German city of Heidelberg, said police, adding that it did not appear to be a terror attack.
The driver is said to be in a serious condition in hospital.
Police shot and injured the man, who was armed with a knife, after a brief standoff.
The motives for the attack remained unknown. The suspect, armed with a knife, left the auto and went toward the Bergheimer street, where he was identified by a police unit. Schaetzle did not confirm whether the man was mentally disturbed, but said that that the perpetrator likely acted alone.
Iraq launches offensive to recapture Mosul from Islamic State
The battle for Mosul launched in late October, and US -backed Iraqi forces retook the eastern half of the city in late January. About 160,000 civilians have been displaced from the Mosul area since the start of the battle in October, U.N. officials say.
Local media report that the suspect was driving a rental auto. The city is primarily known as a university town - about a quarter of its 150,000 residents are students.
German authorities are on high-alert after a man drove a truck into Christmas crowds at a Berlin market, killing 12 people. In July 2016, a similar attack in Nice, France, left 86 people dead.
Police spokeswoman Anne Baas said one of the three people hit outside a bakery was also seriously injured.
