Updated at 5:10 p.m. ETSyria's foreign minister said Monday that the government supports a new Russian-backed deal to create "de-escalation zones," though it does not support the presence of international forces to enforce them.But it remains to be seen whether this latest international effort will be any different than numerous other attempts that have thus far failed to end the six-year conflict.Later Monday, U.N. mediator Staffan de Mistura said he is convening a new round of talks in Geneva between the Syrian government and opposition on May 16.This track is separate from the Russia-backed deal signed last week in Astana, Kazakhstan, though de Mistura said in a statement that he hopes the Astana agreement "will be implemented in full — thus bringing about a significant de-escalation in violence, and helping shape an environment conducive to the political intra-Syrian talks in Geneva."The Astana agreement "foresees four de-escalation zones between rebels and pro-government forces," NPR's Alison Meuse reports from Beirut. "Regional heavyweights Iran and Turkey, which back rival sides, have also backed the deal."It gives Russia, Iran and Turkey until June 4 to map out the boundaries of the de-escalation zones.Syrian Foreign Minister Walid al-Moallem "asserted that there will not be international forces under the supervision of the UN, and the Russian guarantor clarified that military police forces will be deployed, according to Syrian state media.While his comments were not explicit, they seemed to suggest that the Syria government expects its allied Russian forces to enforce the de-escalation zones, which would initially be set up for six months.The agreement also calls on the parties to continue fighting ISIS and groups linked to al-Qaida. "The de-escalation zones are intended to shore up a partial cessation of hostilities brokered by Russia and Turkey at the end of last year, which both sides have accused each other of violating repeatedly," the BBC reports."The agreement to halt air strikes on the designated rebel areas is already in forces and strikes have dropped off, according to the Syrian Observatory for Human Rights," Alison reports. But she adds that government forces continue to consolidate their gains near the capital.The current deal has some similarities with previous attempts that fell apart, as Alison explains:
