US forces in armored vehicles conducted a patrol on the Syria-Turkey border on Thursday, Reuters reported, citing a Syrian Democratic Forces (SDF) military source and witnesses.
If confirmed, this would be the first such exercise since a US decision to withdraw from northeast Syria.
Armored vehicles carrying a US flag were seen near the Syria-Turkey border.
A military source from the Kurdish-led SDF said the patrols would not be a one-off occurrence.
