Russian reports have alleged that French military personnel, potentially from the French Foreign Legion, are participating in combat operations in Ukraine. Citing security service sources, Russian news agency TASS suggested that casualties among these professional military members could range from dozens to several hundred. The French Ministry of Defense has dismissed these claims, labeling them as part of a Russian disinformation campaign.

Following these reports, the Russian Embassy in Paris issued a warning to French citizens regarding service in Ukraine. Using the proverb, ‘He who takes up the sword shall perish by the sword,’ the embassy cautioned individuals considering fighting as mercenaries on behalf of the Ukrainian government.
