According to a report by police, several people have been killed and a number of others injured after a car drove into pedestrians in the German city of Trier.
At least two people died and 15 others were injured in the collision, which happened in a pedestrianised area of the city centre on Tuesday, Trier Mayor Wolfram Leibe said.
Armed police, several ambulances and the fire service are currently at the scene, along with the mayor and two helicopters circling overhead, reported Trierischer Volksfreund.
“We have a driver who ran amok in the city. We have two dead that we are certain of and up to 15 injured, some of them with the most severe injuries,” Mr Leibe told a news conference this afternoon.
The 51-year-old driver, who is from the Trier-Saarburg district, has been arrested and the large hatchback vehicle seized, police added.
Police have not established the motive behind the attack, which comes on the same day Germany went into a second lockdown.
A force spokesman said on Twitter that “several” people were killed in the incident, with local media reporting four dead, including a child.
“I just walked through the city centre and it was just horrible. There is a trainer lying on the ground, and the girl it belongs to is dead,” he added.
An eyewitness told Trierischer Volksfreund that the vehicle drove from the city’s famous Roman gate – the Porta Nigra – along a shopping street towards the main market and then onto Fleischstrasse, where it hit several pedestrians.
Another told the newspaper they saw a pram fly through the air at the market before passers-by flooded into her shop trying to escape.
Police were finally able to stop the vehicle in nearby Christophstrasse, the eyewitness added.
A video circulating on social media shows a number of police officers pinning a man to the ground next to a silver SUV, which appears to have been badly damaged by the impact of the crash.
Emergency services urged people to stay away from the city centre, where a large cordon is still in place, local reports said.
Trier is around 120 miles west of Frankfurt, on the German border with Luxembourg.
It is four years since a terrorist drove a truck through a Christmas market in Berlin, killing 12 shoppers.
