From Bloomberg, "France to Probe Possible Russian Influence on Yellow Vest Riots":

France opened a probe into possible Russian interference behind the country's Yellow Vest protests, after reports that social-media accounts linked to Moscow have increasingly targeted the movement.
According to the Alliance for Securing Democracy, about 600 Twitter accounts known to promote Kremlin views have begun focusing on France, boosting their use of the hashtag #giletsjaunes, the French name for the Yellow Vest movement. French security services are looking at the situation, Foreign Minister Jean-Yves Le Drian said Sunday in a radio interview with RTL.

Russia has been criticized for using social media to influence elections in the U.S. and elsewhere. Attempts to use fake news reports and cyberattacks to undercut the 2017 campaign of French President Emmanuel Macron failed, but Russian-linked sites have pushed questionable reports of a mutiny among police, and of officers' support for the protests.

The media is furious Russian media is covering these protests.
