Axe attack on a train in Germany.
Reports are saying 20 injured but from what I understand most of those are suffering from shock as opposed to direct physical injury; unreliable but seemingly more up to date stories point it as four people suffering from serious injuries.
What all German media I have checked this morning report are 4 seriously injured, one light injury, 14 people suffering from shock, 1 dead attacker, for a total of 20.
As for a possible islamistic background, here's the relevant part of the Bild article:
Der Täter attackierte die Passagiere mit einer Axt und einem Messer. Ein Sprecher des bayerischen Innenministeriums sagte, er schrie während der Tat „Allahu Akbar” (Gott ist groß).
„Es gibt schon Zeugenaussagen, die auf einen islamistischen Hintergrund deuten könnten. Das ist aber noch keineswegs erwiesen”, sagte der bayerische Innenminister Joachim Herrmann (CSU) im ZDF. Die Ermittler prüfen einen islamistischen Hintergrund
In short: Witnesses (Tagesschau only mentions one witness making that claim) claim the attacker shouted "allahu akbar" during the attack, but there is no proof yet of an islamistic terrorist motive. Police are still investigating.According to public broadcaster ARD
the four seriously injured victims are all from Hong Kong. If that means anything concerning the attacker's motive or if it was just coincidence I have no idea.
EDIT: Just now (TV interview, 9am German time) the Bavarian minster of the interior (i.e. the minister in charge of Bavaria's police) stated that a hand-painted ISIS flag has been found in the home of the attacker, but he also cautioned that it was too early to speak of a terrorist attack, as it is still unclear if the attacker had radical islamistic motives, thought of himself as a jihadist or terrorist, or had perhaps quite different motives.
