Horrifying footage shows the aftermath of a car driving into a crowd of people with at least one dead and numerous injured, including five in a critical condition.
The small silver Renault Clio car drove into a crowd of people and smashed into a shopfront in a busy shopping suburb of western Berlin, on the corner of Rankestrasse and Tauentzienstrasse, on Wednesday.
A man believed to be the driver of the vehicle has been detained, police have confirmed.
At least one person has been killed and around 30 are injured, Martin Dams, spokesperson for the German capital's police said.
A medical helicopter was seen lifting off from the area, usually a popular place for shoppers.
According to unconfirmed information from WELT News, the dead person is said to be a teacher who was there with a group.
"A man is believed to have driven into a group of people. It is not yet known whether it was an accident or a deliberate act," police said, adding that he was being held at the scene.
Police said there are around 130 emergency personnel on-site and that the vehicle in question has been secured.
Images show blankets covering what appears to be a body in an area cordoned off by police.
Further pictures show emergency workers moving apparently conscious people on stretchers towards an ambulance, including one woman sitting up, and another who covered her face with her hand.
According to witnesses, the driver of the Renault initially ran away before he was apprehended by passersby and handed over to the police.
The area is close to Breitscheidplatz, where 12 people were fatally killed when a truck driver deliberately drove into a crowd of people visiting a Christmas market in December 2016. The attacker was later killed and IS claimed responsibility for the attack.
Following the 2016 attack, the square was reinforced to safeguard it and protect the large numbers of people who pass through it every day.
Actor John Barrowman, who happened to be at the scene on Wednesday with his husband Scott Gill, told Sky News he saw the person come on the pavement by the Levi store and the bank.
They then, he continued, "drove onto the street, hit the person and killed them in the street, then came back onto the kerb, went down the kerb, through the cafe area and then into the storefront."
Mr Barrowman said while they are not experts, it appears to be intentional with the way the car mounted the pavement.
Mr Gill said it was sheer chaos, with chairs and tables smashed everywhere along the pavement.
