President-elect Donald Trump tweeted Friday evening asking "when will the U.S., and all countries, fight back" against a "purely religious threat," pointing to the suspect in the recent fatal Berlin terror attack.

"The terrorist who killed so many people in Germany said just before crime, "by God's will we will slaughter you pigs, I swear, we will......" Trump wrote Friday evening.


"slaughter you. This is a purely religious threat, which turned into reality. Such hatred! When will the U.S., and all countries, fight back?" he followed up.

Anis Amri, who was suspected of driving a truck into a crowd at a Berlin Christmas market Monday, killing 12 and injuring dozens more, was killed in a shootout near Milan, Italy, on Friday.

The attack in Berlin was similar to the July 14 attack in Nice, France, where Mohamed Lahouaiej Bouhlel, 39, drove a truck into a crowd celebrating Bastille Day. Eighty-five people were killed and 434 injured.

ISIL has claimed responsibility for both the Nice and Berlin attacks.
