Berlin Christmas market attack suspect Anis Amri shot dead in Milan

The Berlin truck attack suspect was shot dead by police in Milan this morning.

Anis Amri, 24, pulled out a gun after being stopped by cops at 3am local time and was killed in a shootout, officials say.

The Tunisian national was suspected of driving a truck into a packed Christmas market on Monday, killing 12 people and injuring 48.

There is 'absolutely no doubt' that the man gunned down by officers today was Amri, Italian interior minister Marco Minniti said at a news conference.

A police source said earlier the suspect was identified by his fingerprints.

The Islamic State has acknowledged death of the Berlin Christmas market attacker, according to a posting by its Amaq news agency.

''The executor of the Berlin attacks carries out another attack on Italian police in Milan and is killed in a shoot-out,'' the statement said.

It comes as the German Federal Police Office has released a new picture of Amri.
