TOPSHOT-PALESTINIAN-ISRAEL-CONFLICT-CLASHES

TOPSHOT - A masked Palestinian youth wearing a Hamas headband uses a sling-shot to throw back a tear gas canister towards Israeli forces during clashes outside the Israeli-run Ofer military prison, near the West Bank city of Ramallah, on November 18, 2014. Today's deadly attack on a Jerusalem synagogue marked a new level in the violence plaguing the city but a tough Israeli response could trigger further escalation, experts say. After two Palestinians burst into the synagogue armed with a gun and meat cleavers, killing four worshippers and wounding nine other people, Prime Minister Benjamin Netanyahu pledged a harsh response to the brutal murders.
