Syria’s main opposition umbrella group was meeting in the Saudi capital on Monday as Washington and Moscow worked to secure a ceasefire.
“There is a meeting,” Monzer Makhous, a spokesman for the High Negotiations Committee (HNC), told AFP in Riyadh.
The meeting is expected to continue for two or three days to discuss developments since the group decided to attend peace talks in Geneva last month, Makhous said.
He did not give further details.
World powers, which have been pushing for a halt to Syria’s nearly five-year war, had hoped to see a truce take effect last Friday but have struggled to agree on the terms.
