A man wielding an axe injured more than 20 people on a train in Germany after he went on a rampage. The incident occurred in Würzburg-Heidingsfeld, in southern Germany. The train line was immediately shut down while helicopters circled over the area. The alleged perpetrator, thought to be a 17-year-old Afghan citizen and unaccompanied minor refugee, was shot dead by police when he tried to escape, according to a police spokesman. Four people were seriously injured in the attack, and as many as 14 were being treated for shock.
