German police on Thursday arrested four suspects, including a Syrian teenager, over a foiled attack at a synagogue on the holiest day of the Jewish year, a plot officials said was likely Islamist motivated.
The case revived memories of an attack two years ago outside a synagogue in the eastern German city of Halle, when a neo-Nazi gunman sought to storm the Jewish temple while worshippers were inside marking Yom Kippur.
Heavily armed police were deployed to the synagogue in the western city of Hagen on Wednesday as Jewish holiday began at sunset.
