A 42-year-old rabbi was stabbed in an attack near Germany's financial district in Frankfurt, police said on Saturday.
The police said the rabbi, who managed to get to a nearby hospital after the attack, had been approached on a street in Frankfurt's upscale Westend quarter on Friday by a man he believed was speaking Arabic.
When the rabbi stopped to ask the man what he wanted, the assailant pulled out a pocket knife, uttered a death threat in German and stabbed him in the abdomen. The assailant and two women with him then fled.
The police said the rabbi, who is a member of the local Jewish community, was operated on in hospital shortly after the 8:30 pm attack and the injuries were not critical.
Such knife attacks on streets in Germany are exceptionally rare, although there have been some isolated incidents of Jews being assaulted in Berlin in recent years.
