Israeli Prime Minister Benjamin Netanyahu says Israel will not allow Syria's new army or the insurgent group that led the ouster of former President Bashar Assad to "enter the area south of Damascus" as his government made clear Israeli forces would stay in parts of southern Syria for an indefinite period.

Netanyahu's comments Sunday at a military graduation led to new concerns over the Israeli presence, and sway, in a swath of southern Syria as Damascus' new leaders attempt to consolidate control after years of civil war.
