The ISIS website Amaq Tuesday night reported the terrorist organization's claim of responsiblity for the Berlin attack Monday in which 12 people were killed and 48 injured when a racing truck rammed into a Christmas market. The killer is at large and armed, placing Berlin and other German cities, state institutions and transport systems on high alert for further terror attacks, after the first suspect was released for lack of proof linking him to the crime. Most markets have closed. Among the seriously wounded is an Israeli man. His wife is still listed as missing.
