Tuesday's frenzied attack on Jewish worshippers at a synagogue in Jerusalem, in which Palestinians shot and hacked four rabbis to death, is shocking even for this part of the world.
Two Palestinian men used meat cleavers and a gun to carry out the gruesome attack, which also left eight people wounded. The assailants were later shot dead by police. An officer who responded to the attack died of his injuries late Tuesday night.
