UN still has "a million questions" on Syria after Astana deal

The United Nations still has "a million questions" about a Syria deal struck last week by Russia, Turkey and Iran, with a reported reduction in the fighting but aid convoys remain almost totally stalled, a U.N. aid official said Thursday.

"Now Russia and Turkey and Iran explained to us today and yesterday... that they will work very openly, proactively with United Nations and humanitarian partners to implement this agreement," U.N. Syria humanitarian adviser Jan Egeland told reporters after a weekly task force.

"We do have a million questions and concerns but I think we don't have the luxury that some have, of this distant cynicism, and saying it will fail. We need this to succeed."
