French Foreign Minister Jean-Marc Ayrault on Friday hailed "real progress" in Syria but said Geneva peace talks cannot resume unless the ceasefire is fully respected and until all Syrians have access to aid.

"We want a speedy resumption of the negotiations in Geneva, but two conditions must be fulfilled: access for all Syrians to humanitarian aid, and full respect of the ceasefire," Ayrault said after meeting with his British, German and EU counterparts.
