In the lead-up to the Paris 2024 Olympics, French intelligence is investigating suspected sabotage of the railway system, which has disrupted travel for approximately 800,000 people. Investigators are focusing on far-left and environmentalist groups as potential perpetrators, citing their methods that align with previous radical actions. Security analysts have also raised concerns about possible Russian involvement, suggesting that discontent over Russia's exclusion from the Games could motivate sabotage attempts. The coordinated arson attacks occurred just hours before the Olympic opening ceremony, targeting strategic rail points to maximize disruption. Authorities have yet to identify any suspects or claim responsibility for the attacks, while a Franco-Swiss airport experienced temporary evacuation due to security concerns. Eurostar has advised passengers to avoid travel as services between London and Paris face cancellations and diversions due to the chaos.
