The latest developments in the terrorist attack in Berlin show a specific and intentional act of Jihad against the German Christmas Market. ISIS has claimed responsibility:
(Via Daily Beast) A “soldier” of the Islamic State carried out the truck attack in Berlin on Monday evening, the terrorist group claimed through its unofficial news agency. Twelve people were killed and dozens more injured when a hijacked truck loaded with steel crashed into a popular Christmas market. A suspect was detained near the scene by German authorities but released on Tuesday, when they said they did not have proof he was the individual driving the truck.
