Two people have died and another 15 have been injured after a car ‘deliberately’ ploughed into them on a German street.
Emergency services were called to the scene in the pedestrianised area of Trier after a Range Rover was seen speeding through at around 40mph.
The dark grey 4x4 crashed into several people - and a baby’s pram - leaving them badly hurt on the pavement on Tuesday.
A girl is said to be among those killed in the "rampage", with police confirming there were more than two fatalities, the Mirror reports.
The driver of the car - a 51-year-old German man who lives in the area - was arrested during a dramatic takedown when police stopped the vehicle in a street nearby.
There is no known motive at this early stage of the investigation.
Photos posted online show a body covered by a tarpaulin in a pedestrian street decorated with Christmas lights, while a video clip showed an injured person on the floor next to a shop as witnesses signalled for help.
Video posted on Twitter shows police arresting a suspect near to a Range Rover that had significant damage to its front end and appeared to have collided with an unmarked police car during a dramatic takedown.
Public broadcaster SWR reported that the driver had been detained by police, adding that details of the incident,which occurred just after 2pm local time, were unclear.
Police spokesman Uwe Konz told Bild: "We can't say anything about the background, whether it's terror or the like."
Mayor Wolfram Leibe, who was overcome by tears as he spoke to reporters, described the incident as a "rampage".
He said: "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.
"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."
Mr Leibe said he did not know the motive for the incident.
A witness told the Trierischer Volksfreund newspaper the Range Rover was driving at high speed and people had been thrown through the air.
Another witness, who was watching from her store, told the newspaper she saw a baby carriage fly through the air as victims were run down at the main market.
People ran screaming into her shop in a panic as they tried to find a safe place.
A male victim who was hit by the Range Rover died in front of a store nearby, while a female victim died at another location close by, the report added.
A police spokesperson tweeted: "We arrested one person and secured a vehicle.
"According to initial investigations, two people have died.
"Please continue to avoid the city centre."
A Christmas market that is usually held in Trier was cancelled this year due to the pandemic.
The force said "several" people were injured.
It added in a later tweet: "Several dead and injured in downtown Trier.
"A driver is captured. Care for the injured has absolute priority."
A report by the Lokalo news website claimed the pedestrians were hit by a Range Rover that was travelling at about 40mph at one point.
The city centre was cordoned off and helicopters were circling overhead.

A spokesman for Chancellor Angela Merkel said: "What happened in Trier is shocking.
"Our thoughts are with the relatives of the victims, with the numerous injured and with all those who are on duty now to care for those affected."
The incident happened at a time of year when German cities and towns are usually busy hosting Christmas markets.
This year's events have been shuttered by the coronavirus pandemic and government restrictions, however.
Known for its well-preserved Roman structures, including a gate and bridge, Trier is located in the Moselle wine region, near Germany's border with Luxembourg border.
The city is home to just over 110,000 people and about 100 miles west of Frankfurt.
