Who is Magdeburg market attack suspect Taleb al-Abdulmohsen?
On Friday evening, a man ploughed a car into a crowd of shoppers at a Christmas market in the German city of Magdeburg.
The attack has left five people dead and more than 200 injured, with many in a critical condition.
One man has been arrested over the attack, and police believe he was solely responsible.
German Chancellor Olaf Scholz travelled to Magdeburg on Saturday, and a city councillor declared Christmas over for the city.
How did the attack unfold?
Unverified footage on social media showed a black BMW travelling at high speeds through the pedestrian walkway between Christmas stalls.
Eyewitnesses described jumping out of the car's path, fleeing or hiding. One told the Reuters news agency that police were already at the venue and chased after the car before arresting the suspect.
Footage from verified sources showed armed police confronting and arresting a man who can be seen lying on the ground next to a stationary vehicle - a black BMW with significant damage to its front bumper.
BBC correspondent Damien McGuinness in Magdeburg reported that the market is "surrounded by concrete blocks". However, "there is a gap which is wide enough for pedestrians to go through, but tragically wide enough for a car to go into the Christmas market", he said.
City officials said around 100 police, medics and firefighters, as well as 50 rescue service personnel rushed to the scene in the aftermath of the attack.
Images from the scene on Friday night showed an area outside the market awash with blue lights as dozens of first responders attended to the injured.
Who are the victims?
Five people have died in the attack, one of whom is a child.
More than 200 people have been injured and at least 41 are in a critical condition.
The toll had earlier been reported as two dead and 68 injured, but was revised to the much higher totals on Saturday morning.
None of the victims have been identified yet.
Who is the suspect?
German media has identified the suspect as Taleb A, a psychiatrist who lives in Bernburg, around 40km (25 miles) south of Magdeburg.
The motive behind the attack remains unclear, but authorities have reported that they believe he carried out the attack alone.
Originally from Saudi Arabia, he arrived in Germany in 2006 and in 2016 was recognised as a refugee.
He ran a website that aimed to help other former Muslims flee persecution in their Gulf homelands.
Evidenced by social media posts, the suspect is an outspoken critic of Islam, and has promoted conspiracy theories regarding a plot to seek Islamic supremacy in Europe.
A report from Der Spiegel said a complaint was filed against Taleb A with the authorities a year ago over statements he made. Officials did not see any concrete threat, the report says.
What have officials said about the attack?
"The reports from Magdeburg raise the worst fears," the German chancellor, Olaf Scholz, said on social media platform X.
Magdeburg's city councillor for public order, Ronni Krug, said the Christmas market will stay closed and that "Christmas in Magdeburg is over", according to German public broadcaster MDR.
That sentiment was echoed on the market's website, which in the wake of the attack featured only a black screen with words of mourning, announcing that the market was over.
The Saudi government expressed "solidarity with the German people and the families of the victims", in a statement on X, and "affirmed its rejection of violence".
UK Prime Minister Sir Keir Starmer said he was "horrified by the atrocious attack in Magdeburg", adding that his thoughts were with "the victims, their families and all those affected" in a post on X on Friday night.
