UN special envoy to Syria, Kofi Annan, said he is "optimistic" about making diplomatic progress after meeting with President Bashar al-Assad again on Sunday but that a deal could be tough to secure.
"It's going to be tough, it's going to be difficult but we have to have hope," Annan said after wrapping up two days of talks in Damascus, according to CNN.
A UN official told CBS News that Annan had strong hopes he managed to make an advance in solving the crisis. "He ended very candid, positive talks with Assad, and he feels very optimistic that he is making a breakthrough," said the source, who spoke on condition of anonymity, told CBS.
