German police step up search for Berlin truck attack suspect
An international manhunt is under way for an "armed and dangerous" Tunisian man with ties to Islamic extremists who has been identified as a suspect in the Berlin Christmas market attack which left 12 dead.
A €100,000 (£84,000) reward is being offered for information leading to the arrest of Anis Amri.
It emerged the 24-year-old was under covert surveillance by German authorities for more than six months after they received a tip in March that he may have been planning a break-in to finance buying automatic weapons for an attack.
But agencies stopped watching him in September after nothing was found to substantiate the original warning.
The German Interior Minister said asylum seeker Amri was suspected of involvement in Monday's terrorist outrage, but was not necessarily the man who drove the hijacked lorry into a crowded Christmas market in Berlin.
