Foreign ministers from the Middle East, Europe and the US have been meeting today in Jordan to try to hammer out a united approach to diplomacy with the Islamist rebel forces now in charge in Syria.
US Secretary of State Antony Blinken and his Turkish counterpart were both at the summit. Turkish-backed rebels in the north of Syria have already clashed with US-backed Kurdish forces who control some of the country's largest oil fields.
Speaking after the meeting, Mr Blinken said the US was determined to help Syrians live up to the promise of this moment, and confirmed that the US has already been in contact with the HTS rebels.
