A Jewish man wearing a kippa skullcap was stabbed in the eastern French city of Strasbourg Friday by a man who was promptly arrested, police said.

The man, who is in his sixties, was stabbed in the abdomen outside his home in the city's Jewish quarter, Strasbourg's chief rabbi Rene Gutman told AFP.

His injuries were not life-threatening, Gutman added. Police have not commented on the motive for the attack.

The rabbi cited witnesses as saying the victim's alleged assailant, who police said has a history of mental health problems, shouted "Allahu Akbar" (God is Greatest).

Gutman also said the suspect had previously attacked a member of the local Jewish community in 2010.

Condemning the attack, he said it "in no way reflects the prevailing climate in Strasbourg."

The local prosecutor's office confirmed the arrest and said an investigation had been launched.
