Germany's foreign minister is calling for strengthened efforts against anti-Semitism to ward off the possibility that many Jews decide to leave the country. Maas' comments came a day before the 75th anniversary of the Soviet liberation of the Nazis' Auschwitz death camp and at a time of rising concern in Germany and elsewhere in Europe about anti-Semitism. In October, a man tried to force his way into a synagogue in Halle on Judaism's holiest day, later killing two passers-by before being arrested.
