New round of Syria international talks to be held in New York: Ban Ki-moon

The international talks will bring together for the first time key players Russia, the United States, Iran and Saudi Arabia

A new round of international talks on ending the war in Syria will be held in New York, just weeks before a ceasefire and peace negotiations are to be launched, UN Secretary-General Ban Ki-moon said today.

Ban did not announce a date for the meeting, but diplomats said it was likely to be held on December 18.

"Member-states are very closely coordinating to have the third Vienna process meeting here in New York," Ban told reporters. "I'm looking forward to that."

Diplomats from 17 countries have held two meetings in Vienna to agree on a roadmap to end the nearly five-year war in Syria that has left 250,000 dead and triggered a refugee crisis in Europe.

There had been concerns that the row between Russia and Turkey over the downing of a Russian fighter plane could have jeopardized the Vienna talks, but Ban's announcement indicated that the peace effort was on track.

The international talks bringing together for the first time key players Russia, the United States, Iran and Saudi Arabia mark the most significant push to date to try end the war.

At the last meeting on November 14, countries agreed on a path to elections in 18 months and a political transition within six months.

Ban said the aim was to declare a nationwide ceasefire and launch political talks between the Syrian government and the opposition in early January.

"The Vienna peace process has created new momentum," Ban said.

"We are working to launch an initiative in early January that would involve both intra-Syrian political talks and a nationwide ceasefire."

Major differences remain, however, between the powers at the Vienna table over the fate of Syrian leader Bashar Al-Assad, with Russia and Iran refusing to support Western calls for him to step down.

Ahead of the New York meeting, Saudi Arabia is due to host a meeting of Assad's armed and political opponents, although no date has been announced for those talks.

Jordan is preparing a list of opposition groups who will have a seat at the negotiating table, making the distinction between those with a political stake in Syria's future and "terrorists" who will be left out.
