Magdeburg (Germany), 21 Dec

A car plowed into a busy outdoor Christmas market in the eastern German city of Magdeburg on Friday, killing at least two people and injuring at least 60 others in what authorities called a deliberate attack.

The driver was arrested at the scene shortly after the car barrelled into the market at around 7pm, when it was teeming with holiday shoppers looking forward to the weekend.

Verified bystander footage distributed by the German news agency dpa showed the suspect's arrest on a walkway in the middle of the road. A nearby police officer pointing a handgun at the man shouted at him as he lay prone. Other officers soon arrived to take the man into custody.

The two people confirmed dead were an adult and a toddler, but officials said additional deaths couldn't be ruled out because 15 people had been seriously injured.

The violence shocked the city, bringing its mayor to the verge of tears and marring a festive event that's part of a centuries-old German tradition. It also prompted several other German towns to cancel their weekend Christmas markets as a precaution and out of solidarity with Magdeburg's loss.

The suspect is a 50-year-old Saudi doctor who moved to Germany in 2006, Tamara Zieschang, the interior minister for the state of Saxony-Anhalt, said at a news conference. He has been practicing medicine in Bernburg, about 40 kilometers (25 miles) south of Magdeburg, she said.

“As things stand, he is a lone perpetrator, so that as far as we know there is no further danger to the city," Saxony-Anhalt's governor, Reiner Haseloff, told reporters. "Every human life that has fallen victim to this attack is a terrible tragedy and one human life too many."

The violence occurred in Magdeburg, a city of about 240,000 people west of Berlin that serves as Saxony-Anhalt's capital. Friday's attack came eight years after an Islamic extremist drove a truck into crowded Christmas market in Berlin, killing 13 people and injuring many others. The attacker was killed days later in a shootout in Italy.

Christmas markets are a huge part of German culture as an annual holiday tradition cherished since the Middle Ages and successfully exported to much of the Western world. In Berlin alone, more than 100 markets opened late last month and brought the smells of mulled wine, roasted almonds and bratwurst to the capital. Other markets abound across the country.

German Interior Minister Nancy Faeser said late last month that there were no concrete indications of a danger to Christmas markets this year, but that it was wise to be vigilant.

Hours after Friday's tragedy, the wail of sirens clashed with the market's festive ornaments, stars and leafy garlands.

Magdeburg resident Dorin Steffen told dpa that she was at a concert in a nearby church when she heard the sirens. The cacophony was so loud “you had to assume that something terrible had happened.”
