Syria's opposition indicated on Wednesday it was ready for a two-week truce in Syria, saying it was a chance to test the seriousness of the other side's commitment to a U.S.-Russian plan for a cessation of hostilities.
Combatants are required to say whether they will agree to the "cessation of hostilities" in the five-year war by noon on Friday (1000 GMT), and to halt fighting on Saturday. The United Nations hopes the planned halt will provide a breathing space for Syrian peace talks to resume.
A statement seen by Reuters from the Saudi-backed High Negotiations Committee, which groups political and armed opponents of Syrian President Bashar Assad, said it "views a temporary two-week truce as a chance to establish how serious the other side is in committing to the points of the agreement."
But it objected to Russia being a guarantor of the truce alongside the United States, saying Russia was a direct party to the conflict, and that the plan ignored the role Assad allies Russia and Iran were playing.
