At least two people have been killed and dozens injured after a man allegedly rammed the car he was driving into crowds at a Christmas market in the east German city of Magdeburg, in what authorities are treating as an attack.
At least 60 people were injured in the violence on Friday night (local time), said Reiner Haseloff, premier of the state of Saxony-Anhalt, where Magdeburg is the capital. One of the dead was a young child, Haseloff added.
The suspected driver of the vehicle has been arrested, Haseloff has confirmed.
How did the incident unfold?
The eastern city of Magdeburg is located about 130km southwest of Berlin. People had gathered at the markets to celebrate in the days leading up to Christmas.
German news outlet Der Spiegel, citing security sources, said that a black BMW had barrelled through the crowd at high speed just after 7pm Friday local time (5am Saturday AEDT) when the market was filled with revellers.
A video posted on social media from a position above the market shows a car driving at speed through a crowd walking between two rows of market stalls.
People can be seen knocked to the ground and running away. Reuters said it was able to verify the location, with the trees, outline and design of the buildings matching file and satellite imagery of the area.

Police made one arrest after the vehicle drove "at least 400 metres across the Christmas market", leaving behind a trail of bloodied bodies at the city's central town hall square.
Local television showed ambulances and fire engines at the chaotic site, which was doused in blue light with sirens wailing, as badly injured people were being rushed off to hospitals and others were treated as they lay on the ground.
Cries and screams could be heard as dozens of police, medics and the fire service deployed to the litter-strewn market decorated with Christmas trees and festive lights.
What is known about the suspect?
Haseloff told reporters at the scene that authorities had "arrested the perpetrator", saying the suspect was a doctor from Saudi Arabia who has been in Germany since 2006.
Haseloff said the man had driven a rented car with Munich licence plates into the market.
"From what we currently know, he was a lone attacker, so we don't think there is any further danger for the city."

The suspect was 50 years old, Saxony-Anhalt's regional interior minister Tamara Zieschang said alongside Haseloff. The man lived in Bernburg, some 40km south of Magdeburg, and had "a permanent residence permit", Zieschang said.
How have world leaders reacted?
"Horrific news from the Magdeburg Christmas market in Germany," Australian Prime Minister Anthony Albanese wrote on social media platform X on Saturday morning.
"My thoughts and those of all Australians are with the victims and their loved ones."
German Chancellor Olaf Scholz had written on X shortly after the incident that "the reports from Magdeburg raise the worst fears".
"My thoughts are with the victims and their families. We stand by their side and by the side of the people of Magdeburg. My thanks go to the dedicated rescue workers in these anxious hours."
French President Emmanuel Macron said he was "profoundly shocked" by the attack and that he "shares the pain of the German people".
Italian Prime Minister Giorgia Meloni also said she was "deeply shocked by the brutal attack on the defenceless crowd", adding: "Violence must have no place in our democracies."
Spain's prime minister Pedro Sanchez said he was "shocked" by the "terrible attack".
What happens next?
Authorities were "in the process of gathering all further data and also conducting an interrogation", he said.
Scholz is set to visit the scene on Saturday. Haseloff said he and Scholz would discuss the "necessary measures" to be taken next.
"We now need to work through this and draw long-term consequences," Haseloff said.
