UN peacekeepers withdrew from all of their posts in the Syrian Golan Heights on Monday as regime forces and rebel factions battled for control of the areas adjacent to the Syrian-Israeli border. The UN has called it a ‘deteriorating situation.’ The withdrawal came as rebels gained control of almost the entire Syrian border with Israel a UN spokesperson said. Syrian armed groups posed a ‘direct threat to safety and security.’ Fighting from Syria spilled over into Israel on Monday morning again as a mortar shell struck near the Israeli side of the Quneitra crossing in the Golan Heights. Artillery fire from Syria has landed frequently on the Israeli side of the Golan Heights over the past few weeks. These evacuations mean that there is no longer a 1,200-strong UN force monitoring the buffer zone between Syria and Israel.
