The US is preparing to withdraw all its troops from Syria, US media quoting defence officials report.
One defence official told CNN the planning was for a “full” and “rapid” withdrawal.
There are around 2,000 US troops on the ground in Syria, primarily training local forces to combat the Islamic State (IS) group.
President Trump had promised earlier this year to pull US troops out of Syria “very soon”.
Most US troops are based in the north-east of the country where they had been helping to rid the area of IS.
But pockets of IS fighters remain, and it had been thought US defence officials wanted to stay to ensure the militant group could not rebuild.
