The Syrian military agreed early Thursday to a nationwide ceasefire, including a halt to airstrikes and shelling, set to begin at midnight Friday. President Vladimir Putin said Russia and Turkey will be guarantors of the peace arrangement, and it will be followed by more talks between Syrian President Bashar al-Assad’s government and opposition forces. Separately, Putin ordered an immediate drawdown of Russian forces and weaponry in Syria, though it was unclear how many troops, crucial to Assad’s defense, would be withdrawn. The truce includes 62,000 opposition fighters throughout Syria, said Russian Defense Minister Sergei Shoigu, but excludes groups labeled as terror organizations by the United Nations, including ISIS and al Qaeda-linked factions. Turkish and Russian officials said they have established a new hotline intended to monitor compliance with the peace deal. Until now, all previous efforts to stop the country’s nearly six-year civil war have failed. More than 400,000 people have died in the fighting.
