The Russian Defense Ministry first posted the alleged proof on Tuesday morning, with one black-and-white image showing a top-down gunship view of a series of trucks supposedly leaving the eastern ISIS-held village of Al-Bukamal for the nearby Syria-Iraq border. The images were from the game AC-130 Gunship Simulator, available for iOS and Android.
Soon after people noted the dubious origin of the photographs, the defence ministry deleted its tweets, and removed the photographs from the corresponding Facebook posts.
If the idea of American forces in league with the Islamic State isn't absurd enough, it gets better: One of the screen captures was from a video game.
Researchers at Conflict Intelligence Team, a nonprofit group that investigates Russian military activities, subsequently reported that three other images shared by Russia as "irrefutable evidence" of us forces assisting the Islamic State were actually taken from video released by the Iraqi Ministry of Defense in 2016.
In the corner of the image, however, a few letters of the developer's disclaimer can still be seen: "Development footage. All content subject to change".
This week, Russian Federation took to social media to announce it had "irrefutable evidence" that the United States is helping ISIS.
Russian Federation alleges the U.S. is co-operating with so-called Islamic State by providing cover to fleeing IS militants.
The ministry said US-led coalition planes instead tried to impede Russian Aerospace Forces operations in the area.
A spokesperson for the Russian defence ministry told media it was "carrying out checks on a civilian employee who mistakenly added photographs to the ministry's statement".
The tweet says that "the ministry of defence shows irrefutable evidence that U.S. are actually covering ISIS combat units to recover their combat capabilities, redeploy, and use them to promote American Interests in the Middle East".
Coalition spokesman Col. Ryan Dillon called those claims, "about as accurate as their air campaign".
"So again, that is pretty consistent with what we have seen come out of Russian MOD as being baseless, inaccurate and completely false".
