JERUSALEM (AP) — Israeli police say an Arab assailant has stabbed a Jewish man in Jerusalem.

Police spokesman Micky Rosenfeld says the man was stabbed Monday night outside the old city of Jerusalem and has been taken to hospital in moderate to serious condition. One suspect has been arrested.

He said the incident was being regarded as a terrorist attack.

Israel is in the midst of its worst sustained bout of violence in nearly a decade. Eleven Israelis have been killed in Palestinian attacks over the past month, including five people who were killed in a assault on a Jerusalem synagogue last week.

Attacks have been mostly in Jerusalem but also in Tel Aviv and the West Bank.
