PARIS — Outgoing French Prime Minister Gabriel Attal said that sabotage and arson that hit key parts of France’s high speed rail network on the eve of the Olympics had “a clear objective: blocking the high speed train network.” [time-brightcove not-tgx=”true”] He said the vandals strategically targeted the main routes from the north, east and west toward Paris, hours before the city hosts the Olympics opening ceremony. Speaking to reporters Attal said there will be “massive consequences,” with “hundreds of thousands” of people stuck while trying to visit Paris for the Games or vacations. PARIS (AP) — France’s high-speed rail network was hit Friday with widespread and “criminal” acts of vandalism including arson attacks, paralyzing travel to Paris from across the rest of France and Europe only hours before the grand opening ceremony of the Olympics. French officials condemned the attacks as “criminal actions,” though they said there was no sign of a direct link to the Games, and prosecutors in Paris opened a national investigation saying the crimes could carry sentences of 15 to 20 years. As Paris authorities geared up for a spectacular parade on and along the Seine River, three fires were reported near the tracks on the high-speed lines of Atlantique, Nord and Est, causing disruptions that affected hundreds of thousands of travelers. Among them were two German athletes in showjumping who were on a train to Paris to take part in the opening ceremony but had to turn back in Belgium because of the closures, and will now miss the ceremony, German news agency dpa reported. “There was no longer a chance of making it on time,” rider Philipp Weishaupt, who was traveling with teammate Christian Kukuk, told dpa. French Prime Minister Gabriel Attal wrote on the social media platform X that France’s intelligence services have been mobilized to find the perpetrators. Attal characterized them as “acts of sabotage,” which were “prepared and coordinated.” There were no known reports of injuries. Transport Minister Patrice Vergriete described people fleeing from the scene of fires and the discovery of incendiary devices.
