The US being behind it makes sense, they want ISIS to appear to be a larger threat to push further attacks in the Middle East. ISIS being behind it makes sense, they want to appear more powerful than they are. Russia doesn't make sense. They want the US out of the Middle East and I can't see any real gain on their part.
ISIS is considered by Vladimir Putin to be a bunch of mercenaries paid for by the United States. Russian news shows share this view.
Really this story should be flagged as fake news has no business here.
It is laughable that someone in Moscow was behind a story designed to convince people in Albuquerque that ISIS is about to attack them, from the cybersphere or otherwise.
