The United States and its allies are helping Islamic State (ISIS) terrorists "directly", the Russian defence ministry is quoted by Tass news agency as saying.
Other images posted to Twitter appeared to be taken from videos released by Baghdad's Ministry of Defense in 2016, showing the Iraqi Air Force bombing jihadis near Fallujah, the CIT said. The image went viral nearly immediately, but it was quickly debunked once someone recognized that the image was actually from a 2015 trailer for AC-130 Gunship Simulator: Special Ops Squadron.
The discovery was made by Eliot Higgins, founder of the investigative website Bellingcat, who noticed a large red "fire" button in the corner had been cropped out of the picture.
The ministry later deleted the images.
The ministry said it would investigate the incident, which it said was caused by a civilian employee, but did not say how or why the pictures used were incorrect.More news: Senegal Books Ticket to World Cup Russia
Russia's Defense Ministry earlier on Tuesday published photographs that it said proved that USA forces refrained from launching airstrikes against forces of the Islamic State terror group as they fled Syria's Al Bukamal. "All content subject to change".
"The US 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", the statement concluded.
Hours later, the ministry published an updated statement with a different set of images, which it also said proved their claims.
"Such actions by the coalition show that the rapid advance of the Syrian troops in Abu Kamal have disrupted US plans to create pro-American authorities beyond the control of the Syrian government, and to manage the territories on the eastern bank of the Euphrates", it said.
Responding to Russia's allegations in remarks carried by Reuters, a spokesman for the US-led coalition Col Ryan Dillon said the Russian allegations were "about as accurate as their air campaign".
