The suspected Berlin attacker has been killed in a shootout with police in the Italian city of Milan after more than three days on the run as the most wanted man in Europe.

Peter Frank, the German federal prosecutor, said investigations into Anis Amri’s associates and a possible wider terror network in Germany would continue, after he was linked with two jailed extremist preachers convicted for supporting Isis.

The terror group acknowledged his death with a statement praising “another attack” on Italian police, in an attempt to spin the shooting to their advantage.

Isis also released a video of Amri pledging allegiance to its leader Abu Bakr al-Baghdadi in Arabic and claiming he wanted to avenge Muslims killed by Western air strikes, to “punish pig-eaters” and become a “martyr”.

It remains unclear whether Amri was inspired by Isis propaganda, which tippedhas called for followers to carry out lorry rammings and other attacks, or had direct contact with the group.
