The French government indicated that the high-speed train network operated by SNCF suffered from coordinated acts of "vandalism" that caused severe disruptions, considering the attack on the train network to be a criminal act. The French Minister of Sports affirmed, "We will ensure smooth transportation for all delegations at the Olympics." The French Minister of Transport stated that the Montparnasse train station in Paris was the most affected by the vandalism. There was chaos in French railway stations just hours before the opening ceremony of the Olympic Games in Paris. The French railway company announced a disruption in the high-speed train system due to deliberate and extensive acts of vandalism, as cables necessary for the operation of the high-speed train lines were burned.
Paris police chief stated, "We have reinforced all security systems in the capital." French media reported that 250,000 passengers were affected by the attacks on the high-speed train network. SNCF experienced a "massive, widespread attack aiming to paralyze" its high-speed train network, which is experiencing "significant disorder," as announced by the company just hours before the opening ceremony of the Olympics in Paris. The company clarified in a statement, "We will reroute some trains to conventional lines, but we will have to cancel a large number of routes," indicating that "this situation may last throughout the weekend at least until we can carry out repairs. We need at least two days to restore normal train service." The French Minister of Transport commented, "The attack on the high-speed train lines will disrupt operations until the end of the week." Eurostar announced that trips to and from Paris had been delayed for 90 minutes.
