Syria peace talks: opposition demands UN resolution compliance The umbrella body comprising Syria's principal mainstream opposition groups threatened Saturday to withdraw from peace talks shortly after its delegation arrived in Geneva if the "crimes" of Bashar al-Assad's regime persisted. "If the regime insists on continuing to commit these crimes then the HNC (High Negotiations Committee) delegation's presence in Geneva will not be justified," HNC coordinator Riad Hijab warned in a statement in Arabic posted online.
