BERLIN truck terrorist Anis Amri pledged to "kill crusader pigs" in a sick video released by ISIS this afternoon.

The warped 24-year-old killed 12 and maimed dozens more in a lorry rampage at a German Christmas market on Monday.

But Amri was shot dead by quick-thinking cops in the Italian city of Milan this morning, leading ISIS to announce he was one of its disciples.

Speaking to camera, Amri says: "My message to crusaders bombing Muslims everyday... Their blood will not go in vain.

"We are a nation behind them and will take revenge for them.

Adding his allegiance to terror leader Abu Bakr al-Baghdadi, he continues: "I call on my Muslim brothers everywhere... Those in Europe, kill the crusader pigs, each person to their own ability."

The Tunisian terrorist screamed “Allahu Akbar” before being killed in a hail of bullets by a rookie cop during a dramatic Milan shoot-out.

Amri was brought down by Italian police at 3am this morning after officers asked him to show his ID.

He is believed to have slipped over the border from France by train.

Italian newspaper Il Tempo this afternoon published a picture of Amri’s dead body moments after he was gunned down.

Italy's Interior Minister Marco Minniti this morning confirmed the man killed was "without a shadow of a doubt" Amri.

ISIS's propaganda arm AMAQ has since confirmed Amri was the Berlin attacker.

The 24-year-old pulled a pistol from his backpack and shot at two officers - hitting cop Cristian Movio, 36, in the shoulder.

As he did so he screamed "Allahu Akbar" – Arabic for "God is great".

Amri, who had just arrived in Italy by train from France, was gunned down as he tried to flee after cowering behind a nearby car.

Rookie copper Luca Scata, 29, who was just months into his job, brought down the Tunisian in a hail of bullets.

Politician Minniti said: "Italy is grateful to these two police officers for service rendered to our community."

Forensics teams inspected a police car at the scene as daylight broke this morning while several key pieces of evidence were marked out on the ground.

One of them appeared to be a pistol.

Another was a khaki bag from which Amri pulled the weapon.

Authorities believe the 22 calibre gun used by Amri this morning could be the same one used to shoot dead Polish trucker Lukasz Urban on Monday night.

The body was identified using fingerprints - which were also found in the truck that carried out Monday night's atrocity in the German capital.

German authorities confirmed they are still working to confirm whether he had any accomplices.

Pools of blood were clearly visible on the ground surrounding the shoot-out.

Cops reportedly found a train ticket from France in his backpack, suggesting he had just crossed the border with France.

The ticket suggests Amri had travelled from Chambery in south-east France over the border into the Italian city of Turin.

He arrived at the city's Sesto San Giovanni train station at 1am, two hours before the shoot-out.

Italian cops admitted they had no intelligence to suggest Amri was in the country.

The revelation raises serious questions about continental security after Europe's most-wanted man was able to cross at least two international borders freely.

Nigel Farage was one of the first to comment on Amri's apparent journey through three of Europe's biggest nations.

He tweeted: "If the man shot in Milan is the Berlin killer, then the Schengen Area is proven to be a risk to public safety. It must go."

It comes after a Europe-wide manhunt for the Tunisian thought to have been behind Monday's lorry attack.

German authorities had offered a £84,000 reward leading to Amri's arrest.

Amri had strong links to Italy having moved there from Tunisia five years ago.

His father yesterday told The Times his son had become a jihadist after being radicalised in an Italian prison.

Questions are now being raised about how Amri was able to travel from Germany, through France and into Italy

Mustapha Amri said: "He left Tunisia March 2011 in what is called ‘al-Horqa’, a wave of illegal immigration shortly after the uprising.

“He dropped out of school and travelled to Italy. He was involved in a robbery and a case of burning down a school and camp.

“He spent four years in jail in Italy where he met extremist groups which attracted him.”

Only last night authorities confirmed they had found CCTV of a man believed to be Amri standing in the doorway of a Berlin mosque.

The footage was recorded just hours after the Christmas market attack.

Wearing a jacket and a beanie hat, Amri stood outside the mosque in the German capital's Moabit district.

It has since been stormed by German commandos in a dramatic raid in which stun grenades were used.

Danish Police earlier said a man matching Amri's description had been spotted in Eternitten in Aalborg.

And police are now working on the theory an unsolved Hamburg murder that left cops baffled could have been carried out by Amri back in October.

German paper Berliner Zeitung reports that detectives found similarities between the e-fit of the killer and Tunisian Amri.

"This is another lead we will follow," detectives confirmed.

The murder in Hamburg saw a 16-year-old named only as Viktor E knifed alongside the city's Alster lake.

His girlfriend was able to get away after being pushed into the water but Viktor died in hospital of his wounds.

Cops immediately began to work on the theory the killing had been an ISIS-inspired lone-wolf attack.

The group's AMAQ news agency wrote at the time: "A soldier of the Islamic State stabbed two individuals in Hamburg on the 16th of this month.

"He carried out the operation in response to calls to target the citizens of coalition countries."

An e-fit published shortly after appears to bear a resemblance to Amri.
