Syria now has a good opportunity to reach a political solution to its devastating eight-year war as cease-fires have brought calm to many areas of the country, Syria's chief opposition negotiator said Saturday.

"I think now that we have an opportunity, because nearly in Syria we have a cease-fire now, in the northeast of Syria and the north of Syria, and the efforts of fighting terrorism has achieved good results," Nasr Hariri said during an interview in the Saudi Arabian capital, Riyadh, where he is based.

Hariri, the opposition's chief negotiator in U.N. peace talks, met Friday with the newly appointed United Nations Special Envoy to Syria Geir Pedersen.
