MAGDEBURG, Germany >> 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 believe was an attack.

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

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 23 miles (36 kilometers) 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.

Fifteen of the injured were were hurt very seriously, according to government officials and the city government’s website.

Haseloff said the two people confirmed to have died were an adult and a toddler, but that he couldn’t rule out further deaths.

“But that is speculation now. Every human life that has fallen victim to this attack is a terrible tragedy and one human life too many,” he said.

The suspected attack in Magdeburg, a city of about 240,000 people west of Berlin that Saxony-Anhalt’s capital, 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.
