The full extent to which the Berlin attacker Anis Amri crossed several European borders in his flight from Germany has now become apparent.

Having fled from Berlin, where he had killed 12 people at a Christmas Market on December 19, the 24-year-old jihadist was able to board an overnight bus to the city of Nijmegen, in the Netherlands, before taking another coach to Lyon, in central France.

From Lyon, he took a train to Chambery, in the French Alps, before travelling on to the outskirts of Milan. His luck ran out only when he was stopped in the early hours of the morning at a suburban train station in the Italian city.

His flight across three European borders has called into question the Schengen Agreement, which was signed on June 14, 1985, and the efficiency of European intelligence services. But Mr Amri’s escapade is particularly galling for the French authorities, which only recently extended the country’s state of emergency.

For the 2017 elections, right-of-centre political parties, particularly in the Netherlands (March 15), and France (April 30 and May 7) and Germany (October 22), are expected to capitalise on the successive security failures.
