From the English version of Deutsche Welle.
"The incident occurred on the Breitscheidplatz square, near the location of Berlin's iconic Kaiser Wilhelm Memorial Church along the Kurfürstendamm shopping mile. Nine people are reported to have died as a result of the attack; however, unconfirmed reports state that there may be more fatalities. Up to 50 people have been reported as injured.
The police are treating the incident as an apparent terror attack. The driver of the truck has now been arrested after fleeing the scene earlier."
