BERLIN (AP) – The Latest on the truck attack on a Berlin Christmas market (all times local):

5:45 p.m. – German authorities are offering a reward of up to 100,000 euros ($105,000) for the arrest of a Tunisian man suspected of involvement in the fatal attack on a Christmas market in Berlin. Islamic State had previously claimed responsibility for the Berlin killings and on Friday it acknowledged the death of the man it referred to as “the executor of the Berlin attacks.”

The body of Anis Amri, the suspect in the Berlin Christmas market truck attack, is seen covered with a thermal blanket next to Italian officers in a suburb of the northern Italian city of Milan, Italy December 23, 2016. 8:30 a.m. – German investigators were searching Wednesday for the killer or killers in Monday’s attack on a crowded Berlin Christmas market after a man arrested soon after the rampage was released for lack of evidence and the Islamic State group claimed responsibility. Amri, 24, who had spent time in prison in Italy, was stopped by two officers during a routine police check in the Sesto San Giovanni neighborhood of Milan early Friday, the AP reported. “We had no intelligence that he could be in Milan.”

He failed to produce any identification so the police requested he empty his pockets and his small backpack. Chancellor Angela Merkel, under increasing pressure inside Germany to take a much tougher line on immigration after opening the country’s borders to waves of refugees in 2015, said the Berlin attack raised many questions and promised measures would be taken to improve security.
