Just before the Paris Olympics' opening ceremony, France experienced a series of deliberate arson attacks on its high-speed rail network, causing major disruptions and security concerns. While no casualties were reported, the damage caused extensive delays for both domestic and international travelers converging on Paris for the Games. The attacks, described as "criminal" by authorities, prompted rigorous investigations and heightened security measures. The deliberate nature of the attacks and the meticulous damage caused have led to fears of terrorism, especially given France's history of terrorist incidents. The disruptions have significantly impacted France's rail system, affecting over a million travelers and leading to extensive repair work expected to last throughout the weekend. As a result of the attacks, security has been further tightened in Paris, potentially complicating travel for visitors and casting a shadow over the start of the Games.
