UNITED NATIONS: The U.N. envoy to Syria Wednesday invited Syrians to take part in what he called “thematic” discussions to keep alive stalled efforts to negotiate an end to the war.

“Sadly there is still no consensus on the way forward,” Staffan de Mistura told the U.N. Security Council after two months of meetings with key players in the conflict.

“The U.N. is obliged and all of us are obliged to keep the issue alive,” added the Swedish-Italian diplomat, appointed last year to what many termed “mission impossible.” 

“I now intend to invite Syrians to parallel, or simultaneous, thematic discussions through intra-Syrian working groups.” 

But de Mistura gave no details on when or where the talks could take place, and who exactly might participate. Proposed discussions would focus on protecting civilians, political and constitutional issues, military and security matters, public institutions and reconstruction.

“Such an international initiative will require the support of a contact group and we will get to that at the right time.” 

The envoy said “the fear of black flags over Damascus” – a reference to the ISIS emblem – was driving some to reconsider positions, but said there was still significant disagreement on even the causes of the conflict. 

U.N. Secretary-General Ban Ki-moon said there was an “urgent need for the international community to act now if we want to save and preserve what is left of Syria.

“As the situation deteriorates, Syrians predict that the prospects for achieving a political solution will also fade.”

It was a message that his 68-year-old envoy echoed. There were “profound risks” to failing to act now, de Mistura told the Security Council. Each passing month, he said, “reduces the prospects of ever restoring Syria as a unified state.”

Ban instructed de Mistura in late March to step up U.N. efforts to find a political solution. 

Since then, the envoy has visited China, Turkey, Jordan, Egypt and Iran, which is one of the Syrian regime’s main backers.

He also met Syrian opposition figures in both Amman and Cairo.

De Mistura’s predecessors both resigned after failing at the task of trying to bring peace to the country.

The Security Council has been paralyzed by deep divisions over Syria, with Russia blocking resolutions aimed at putting pressure on Syrian President Bashar Assad to end the war.
