STORY: The shooter later turned himself into Israeli authorities, according to a statement by the police, which did not identify him. Israeli media reported the assailant was a Palestinian from east Jerusalem.
The Old City houses sites that are holy to Jews, Muslims and Christians and is among areas where Palestinians seek statehood. Israel deems all of Jerusalem its capital - a status not recognized internationally.
The attack took place in the early hours of Sunday, as Jews were leaving Western Wall rites marking the end of the Sabbath.
