Latest update: attack suspect shot dead by police in Milan



The Tunisian man suspected of killing 12 people by driving a truck into the Breitscheidplatz Christmas market in Berlin on Monday was killed in a shootout with police in Milan early on Friday morning. Police officers stopped Anis Amri at 3am outside Sesto San Giovanni train station in the Piazza 1 Maggio and requested his ID. He then opened fire and wounded a police officer before he was shot dead.

A video was later posted online by the Amaq news agency which showed Amri pledging his allegiance to Islamic State. These dramatic developments came amid speculation Amri was still in Berlin after CCTV footage released by German broadcaster RBB appeared to show him outside a Berlin mosque the night after the attack. Investigators will now focus on what motivated the 24-year-old in the following days to return to Italy where he first arrived in Europe and spent time in prison. According to Milanese police, Amri arrived in the city at 1am on Friday having travelled via Turin and Chambéry in France.

Monday: Christmas market attacked



Shortly after 8pm local time on 19 December, the truck left the road and drove into crowds at the market in Breitscheidplatz. The truck had a run-up of about 80 metres before crashing into market stalls and shoppers outside Kaiser Wilhelm memorial church. At least 12 people died, including the truck’s registered, Polish driver, Łukasz Urban, who appeared to have fought with the assailant.

First suspect arrested and refugee shelter raided



A 23-year-old Pakistani was arrested at a park near the Christmas market in the hours following the attack. He was released on Tuesday evening after police said they found no evidence against him.

In the early hours of Tuesday morning, police raided a refugee shelter housed in a former hangar of the disused Tempelhof airport. The original suspect had been registered at the shelter.

Manhunt for new suspect

On Wednesday, a European arrest warrant was issued for a Tunisian man with alleged ties to Islamic extremists who was identified as a suspect in the attack.

The wanted notice says Anis Amri should be considered armed and dangerous and appears to have used six different aliases and three different nationalities.

Earlier, German media reported that police were searching for a Tunisian man after an identity card belonging to him was found under the driver’s seat of the truck. Checks were made in the western state of North Rhine-Westphalia, where the suspect had previously been registered at a refugee shelter.

Flats raided in Berlin and Dortmund

In the early hours of Thursday morning police targeted flats in Berlin’s Kreuzberg, Moabit and Prenzlauer Berg districts and a Dortmund apartment where truck attack suspect, Anis Amri, is thought to have temporarily stayed. A spokesperson for Germany’s state prosecutor said afterwards they were unaware of any arrests.

Germany’s interior minister, Thomas de Maizière, said later that fingerprints found in the cabin of the truck matched those of Amri, making it “highly probable” that the Tunisian suspect carried out the attack on the Breitscheidplatz Christmas market.

Amri’s movements

Germany’s security services are facing mounting pressure to explain how Amri could have been able to carry out Monday’s attack in spite of having been under covert surveillance for several months and known to multiple intelligence agencies for apparent ties to Islamic extremists.

The 24-year-old from Tatouine left Tunisia in early 2011 after the Arab Spring protests. After arriving by sea in Lampedusa he was involved in violent incidents at refugee centres and later spent time in several Sicily prisons. Amri reached Germany in July 2015 and shuttled between the state of North Rhine-Westphalia and Berlin. His claim for asylum made in April was rejected by German authorities in consultation with security agencies.
