On Wednesday, a car drove through a crowd of people in Berlin’s busy shopping district. Police are investigating whether this was a terrorist attack. According to Berlin police, at least one person was killed and many others were severely injured.

According to Deutsche Welle, five people sustained life-threatening injuries.

According to Berlin police, emergency responders kept the driver of the car on the spot.

Police say that the car’s driver, a German man of Armenian heritage who is 29 years old, was arrested at first and then handed over to emergency personnel.

The incident occurred on Tauenzienstrasse. This street is well-known for its shopping opportunities in the western Berlin district of Charlottenburg. Berlin’s fire department stated that around 60 emergency personnel were on the scene following the accident.

The incident in Germany quickly sparked speculation about a motive. Many people noted that it occurred near Breitscheidplatz aEUR”, where a man drove a hijacked truck through a Christmas marketplace in 2016, killing 12 people.

Police and other authorities warn against jumping to conclusions about Wednesday’s tragedy, noting that the investigation is only just beginning.
