Italian police arrest 5 linked to Berlin Christmas attacker

Italian police say they have arrested five people connected to Anis Amri, the Tunisian who carried out the 2016 Berlin Christmas market truck attack and was later killed in a shootout with police in Italy.

In a tweet Thursday, police said one of the five was believed to have procured the fake Italian identity papers that allowed Amri, a failed asylum-seeker, to move around Europe.

Amri killed 12 people when he hijacked a truck and drove it into a crowded Berlin Christmas market on Dec. 19, 2016. The attack was later claimed by the Islamic State group. Using fake documents, he fled to Italy and died in a shootout with police near Milan four days later.

The arrests were the latest in a marked uptick in recent police operations targeting suspected extremists.
