NEW YORK (Sputnik) — The Syrian ceasefire agreement brokered by International Syria Support Group (ISSG) co-chairs, the United States and Russia, has been sabotaged by actors on both side of the conflict, UN Special Envoy to Syria Staffan de Mistura told reporters.
"Both the two co-chairs have been de-facto undermined by others who have so far not wanted, or have tried to not deliver on the cessation of hostilities," de Mistura said following an unsuccessful Thursday meeting of the ISSG in New York.
The major part of the ceasefire agreement that both sides sought to undermine were "detaching the armed opposition from al-Nusra and grounding the Syrian air force," de Mistura explained.
Were those two steps implemented, "you would see a different Syria the day after, and we would have [humanitarian aid] convoys moving," he added.
