The International Rescue Committee said the government's advance in southwestern Syria has trapped tens of thousands of displaced Syrians along the frontier with the Golan Heights, which Israel occupied in 1967.
In less than a month, Syrian government forces, backed by Russian air power, have been able to seize control of most of southwestern Deraa province, including the provincial capital of the same name. The group is not party to the agreement between the government and rebels. It went on to deny Israeli media reports that resistance movement Hamas, which has governed the Gaza Strip since 2007, had vowed to curtail the group's activities.
Alongside the military offensive, the government has resorted to "reconciliation" agreements whereby it negotiated capitulation deals in a number of villages to restore government control in the localities that have been in rebel hands for years.
Echoing surrender terms imposed on rebels elsewhere, opposition fighters agreed to give up heavy and medium-sized weapons.
The rebels in al-Quneitra province at the border with the Israeli-controlled territory have agreed either to accept safe passage to the rebel-held province of Idlib in the northwest or to remain in the area on the state's terms, according to details outlined by a Hezbollah-run news outlet and a rebel source. The purported deal would see Russian Federation restrict Iran's presence in Syria-or even evict Iran from Syria-to forestall an Israeli-Iranian war that Moscow surely does not want.
The war is estimated to have killed hundreds of thousands of people, displacing 11 million and forcing some six million overseas as refugees.
With most of Daraa under control, government forces have turned their focus to the area near the frontier with Israel, to clear the last pockets of the opposition. The sound of planes could be heard as shelling continued.
Under it, he told AFP, Syrian government forces accompanied by Russian police would enter the buffer zone. Israeli aid, transferred by worldwide humanitarian groups, flows across a 1974 armistice line to a United Nations -monitored buffer zone where numerous refugees are encamped, hoping Assad's army will steer clear.
Israel Radio reported Wednesday that in addition to talks between the two countries' leaders, mutual work groups have been studying issues such as no-man's land, demilitarized zones and the deployment of Israeli and Syrian forces on both sides of the border.
The regime's recapture of Daraa city would be a huge propaganda win for Syrian President Bashar Assad as the seven-year uprising against him has its roots there.
In a briefing with Israeli reporters, he said Israel had not had a problem "with the Assad regime for 40 years", noting that "not one bullet was sacked on the Golan Heights" in that time.
"There have been conflicts from time to time there and we are naturally concerned about the possibility of a military confrontation between the Iranian and Israeli forces in Syria. we will do our best to prevent tensions from escalating", Dzhagaryan said. Deraa city was the scene of the first major peaceful protests against Assad's authoritarian rule in March 2011 which spiralled into a war now estimated to have killed half a million people.
