"Regarding Abu Kamal, this is not the only case when the USA spares terrorists", Russian Foreign Minister Lavrov was quoted as saying by Russia's official TASS news agency on Tuesday.
The evidence that Russia came forward with on Twitter was said to be "irrefutable proof" of collusion, but those who saw the tweets from the Russian Ministry of Defense Twitter account swiftly pointed out that the proof wasn't as irrefutable as it claimed.
Russia's defence ministry on Tuesday posted images it said proved the U.S. was aiding the Islamic State jihadist group in the Middle East, but social media users pointed out they included a still from a videogame.
The Russian Defense Ministry's allegations that US-led forces refrained from attacking fighters from the Daesh terror group as they fled the Syrian city of Abu Kamal are inaccurate, Operation Inherent Resolve spokesman Col. Ryan Dillon told reporters on Tuesday.
United States oil and gas 'resurgence' expected as global demand grows
IEA cut its crude demand growth outlook by 100,000 barrels a day for this year and next, as the Wall Street Journal reports . Indeed, the IEA also suggests that demand for oil will remain supported by lower prices, going forward.
But the monitor Conflict Intelligence Team (CIT), along with a number of social media users, was quick to compare one of the images with an identical still from the wargame "AC-130 Gunship Simulator: Special Ops Squadron".
"This is the best evidence [Russia's defense ministry] are shameless liars, they take a video game screenshot then claim its from a specific location and date", Mr. Higgins tweeted Tuesday.
Russia's Defence Ministry said on Tuesday an employee had attached the wrong photos to a statement accusing the United States of providing de-facto air cover for Islamic State in Syria after the mistake was spotted online.
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 USA forces assisting the Islamic State were actually taken from video released by the Iraqi Ministry of Defense in 2016.
