article: The victim, identified as Nathan Graff, was knifed multiple times by an unknown assailant on Thursday. His injuries are not life-threatening. The motive for the attack is unclear but police are investigating whether it was a hate crime. Several Israelis have been stabbed by Palestinians in Israel and the occupied West Bank in recent weeks. Mr Graff was attacked outside a kosher restaurant. Police are still searching for the assailant. A statement from Milan's Jewish community said it hoped the attack was an isolated incident. "We have never had problems in Milan. We don't think this was a personal affair - there is nothing to suggest that," the community's co-president Milo Hasbani told reporters, according to Reuters.
