This is not good. At all.
The suspect reportedly shouted “Allahu Akbar” (“God is great”) as he started stabbing passers-by in the town of Grafing, to the south-east of the German city.
The attack took place at around 4.50am (3.50am BST) on Tuesday and the suspected perpetrator was arrested shortly afterwards.
That would be about 6 hours ago.
The political effect here in the USA will be the usual.
