Germans on Saturday mourned both the victims and their shaken sense of security after a Saudi doctor intentionally drove into a Christmas market teeming with holiday shoppers, killing at least five people, including a small child, and injuring at least 200 others.
Authorities arrested a 50-year-old man at the site of the attack in Magdeburg on Friday evening and took him into custody for questioning. He has lived in Germany for nearly two decades, practicing medicine in Bernburg, about 40 kilometers (25 miles) south of Magdeburg. officials said.
The governor of the surrounding state of Saxony-Anhalt, Reiner Haseloff, told reporters that the death toll rose from two to five and that more than 200 people in total were injured.
Several German media outlets identified the suspect as Taleb A., withholding his last name in line with privacy laws, and reported that he was a specialist in psychiatry and psychotherapy.
There were still no answers Saturday as to what caused him to drive into a crowd in the eastern German city of Magdeburg.
Describing himself as a former Muslim, the suspect shared dozens of tweets and retweets daily focusing on anti-Islam themes, criticizing the religion and congratulating Muslims who left the faith.
