Berlin police have yet to even put their hands on the right suspect after a truck ploughed into a Christmas market and left 12 people dead.
But Donald Trump has no doubts about what happened.
Just three hours after Monday’s apparent attack, the US president-elect had branded it the latest outrage in what he sees as a global religious war.
His language was a dramatic departure from how Western leaders generally respond to Islamist extremism but reflected the tone of his campaign.
“Innocent civilians were murdered in the streets as they prepared to celebrate the Christmas holiday,” he declared, in a statement from his office.
“ISIS and other Islamist terrorists continually slaughter Christians in their communities and places of worship as part of their global jihad.”
