On the day of the Paris Olympics opening ceremony, French rail services faced significant disruptions due to coordinated acts of vandalism targeting the high-speed train network. Arson attacks on the lines connecting Paris to key cities like Lille and Bordeaux led Eurostar to advise travelers to postpone their trips, resulting in 90-minute delays and multiple train cancellations. The French railway operator SNCF confirmed that repairs were underway but warned that travel would remain heavily disrupted throughout the weekend. Transport Minister Patrice Vergriete condemned the incidents as criminal, emphasizing the heightened security measures in place for the Olympics, with over 45,000 police and military personnel deployed. Despite the chaos, officials stated there was no immediate link to the Games, and the national police are investigating the acts. Passengers have been offered refunds and alternative travel options, though availability is limited due to the ongoing disruptions.
