So some idiot deliberately drove his car into the crowd at a Christmas market in Magdeburg, killing an adult and a toddler and injuring several others. The police have arrested the suspected perpetrator. He is a doctor of psychiatry from Saudi Arabia who has been legally staying in Germany for the last 18 years and no known connections to any islamist or other extremist groups.
So far the guy's motive is still unknown, could be islamist, could be something related to Palestine, could be a mental health crises. In any case, here in Europe Christmas markets have been a very popular target for terrorists for many years now. In 2016 a Tunesian member of the Islamic state drove a truck into a Christmas market in Berlin, killing 18 and injuring 56 others. In 2018 another member of the Islamic State shot and stabbed 5 people and injured 11 others at the Christmas market in Strasbourg. Two years prior, the same year as the Berlin attack, several people had been arrested in France for planning a bomb attack on Christmas markets. Similar arrests of people connected to Al Quaeda had already been made in 2000, also regarding the Strasbourg Christmas market. Tat are just the ones I could think of off the top of my head.
For perspective, here are the known terrorist attacks in Germany of the last few years (leaving out a few that are hard to classify):
2024 so far, excluding today: 1 x leftwing, 3 x rightwing, 4 x islamist, 1 x related to foreign conflict (Russia/Ukraine)
2023: 1 x leftwing, 13 x rightwing, 2 x islamist (not including a guy stabbing several people in a train who happened to be a Palestinian Muslim but apparently simply was mentally unstable)
2022: 4 x rightwing
2021: 3 x rightwing, 2 x islamist
2020: 4 x rightwing, 3 x islamist
2019: 7 x rightwing, 2 x related to foreign conflicts (Turkey & Nigeria)
2018: 2 x leftwing, 3 x rightwing, 2 x islamist, 5 x related to foreign conflict (Kurds & Syria) ... this was a wild year and several more were hard to classify.
Unsolved attacks on Turkish targets could be either neonazis or Kurdish nationalists. Attacks on synagogues and other Jewish targets could be neonazi, islamist or pro-Palestinian. It's often guesswork when nobody is arrested and there is no confession message. However, overall the main threat is homegrown rightwing extremists.
