An agreement was reached Thursday between the warring parties in Syria for a six-month truce in the rebel-held town of Zabadani and two Shiite towns in the northwest, a monitor told AFP.
"A ceasefire in Zabadani and the villages of Fuaa and Kafraya was agreed under the sponsorship of the UN," Rami Abdel Rahman of the Syrian Observatory for Human Rights told the news agency.
A UN spokeswoman, Jessy Chahine, told AFP, "We can confirm that there were positive developments in the talks, which were facilitated by the UN," but added that it was up to the parties themselves to say if there was a deal to announce.
Pro-government forces launched an offensive to try to recapture Zabadani on the border with Lebanon in July.
This prompted a rebel alliance, including Sunni Muslim extremists belonging to Al-Qaeda, to besiege the Idlib province villages of Fuaa and Kafraya, whose residents are Shiites.
"The agreement for a six-month truce was reached between rebel fighters including Islamist group Ahrar al-Sham and pro-regime forces and their allies of the Lebanese Shiite Hezbollah movement," Abdel Rahman told AFP.
The latest truce marks the third time the sides have agreed on a ceasefire in the area. In late August, Syrian insurgents, the Syrian army and Hezbollah agreed on a 48-hour ceasefire in the Zabadani.
The late August truce marked the second time in two weeks the sides had agreed on a ceasefire, but the earlier truce broke down even after a brief extension.
A Syrian source close to the talks told AFP that after a ceasefire began last Sunday, the accord will see the evacuation of some 10,000 civilians from besieged Fuaa and Kafraya on Saturday and Sunday.
They will be driven out in Red Cross vehicles to regime-controlled areas. In exchange, some 500 rebels will withdraw from Zabadani and head for Idlib province.
