A spokesman for the coalition to defeat the Islamic State fired back on accusations from the Russian Defense Ministry on Tuesday, after it accused the U.S. of providing cover for the terror group in Syria.

"I would say the Russian Ministry of Defense statements are about as accurate as their air campaign," Col. Ryan Dillon, spokesman for Operation Inherent Resolve, told reporters on Tuesday. "And I think that is a reason for them to start coming out with their latest barrage of lies."

Earlier on Tuesday, the MoD had released Twitter and Facebook messages claiming that after Russian and Syrian forces liberated the city of Abu Kamal, the U.S. provided cover for ISIS fighters as they fled.

"This is the irrefutable evidence that there is no struggle against terrorism as the whole global community believes," the MoD said. "The U.S. are actually covering the ISIS combat units to recover their combat capabilities, redeploy, and use them to promote the American interests in the Middle East."

Dillon told reporters that Russia was making the accusations in order to cover for its own battlefield mistakes in Syria.

"They are currently having some setbacks, particularly with the civilian casualty allegations of the 50 who were reportedly killed by their strikes in Aleppo," Dillon said. "You've got what happens with their partners in the Syrian regime in Abu Kamal saying that they liberated the city, and they're not in the city, they're still fighting there and had some setbacks in Deir ez-Zor recently."

He also made light of the discovery that the MoD, in making the accusations, included screenshots of a video game as "evidence" that the U.S. was helping ISIS.

Several Twitter users on Tuesday noticed that an image had been taken from a video snippet of the game AC-130 Gunship Simulator, and that other images were actually old footage of Iraqi air force strikes on ISIS.

"I certainly can't verify, but I've seen the report that one of the pictures came from a video game," Dillon said. "Again, that is pretty consistent with what we have seen come out of the Russian MoD as being baseless, inaccurate, and, you know, completely false."

The MoD has since removed the photos.
