Jerusalem ramps up security

Jerusalem (a city that is about two-thirds Jewish and one-third Muslim) ramped up security after two Palestinian cousins wielding a

gun and butcher knives attacked a synagogue during morning prayers on Tuesday, killing four worshipers and a policeman. Three

dual U.S.-Israeli citizens and a British-Israeli citizen died in the attack before police shot and killed the two assailants. The four

victims were all rabbis. Israeli Prime Minister Benjamin Netanyahu vowed a strong reaction to Tuesday's killings. He characterized the

attack, which drew condemnation from around the world, as the result of a "blood libel" fanned by Palestinian leaders. Even after Palestinian Authority President Mahmoud Abbas condemned the attack, Netanyahu insisted it was "not enough" of a response. authorities were beefing up security around Jerusalem after

Tuesday's attack. The reason for the increased security is to ensure no copycat attacks take place and to make sure that no one on the Israeli side decides conduct a vigilante counter attack. The terror

attack -- the deadliest in Jerusalem since 2008 – follows other violence throughout the region. At the heart of the unrest is the

holy site in the Old City of Jerusalem, known as the Temple Mount by Jews and Haram al-Sharif (the Noble Sanctuary) by Muslims.
