Manbij. The video shows military tanks with SDF flags, some of the men are seen wearing YPG badges.Others in the video are clearly westerners, and can be seen in other videos speaking in American accents. Storyful is, however, unable to confirm if the men are US special forces personnel. SDF are widely reported to be supported by US special forces. Reuters said on June 1 that the Manbij offensive was US backed. The Pentagon’s press secretary, Peter Cook, on May 26 denied that US special operation forces were positioned “on the forward line” in Syria. He did not, however, offer a “specific measurement” of what the forward line was. See Storyful report here. Credit: YouTube/Step News Agency">
