A 31-year-old Palestinian man was seriously wounded in Jerusalem early Wednesday in a stabbing that he said was perpetrated by religious Jews.

The victim, an East Jerusalem resident, told police the incident began when four Jews wearing skullcaps approached him near the ultra-Orthodox neighborhood of Mea She'arim. They asked him for the time, and then proceeded to stab him in the back repeatedly.

A passerby who witnessed the stabbing, which transpired on the capital's Shomrei Emumim street, subsequently called a police patrol car to the scene.

A Magen David Adom emergency services ambulance rushed the man to the Hadassah University Hospital in Ein Karem in serious condition.

Police believe the motive for the attack to have been nationalistic. No arrests have been made as yet in connection with the incident.

In October, police arrested nine Jews suspected of recent assaults against Arabs in Tel Aviv and Jerusalem, including several firebombings that set several homes ablaze.
