French rail lines disrupted by ‘coordinated sabotage’ ahead of Paris Olympics opening ceremony

France’s high-speed train lines were targeted by multiple “malicious” acts including arson on Friday, in what has been described as “an attack on France” and “coordinated sabotage” to disrupt travel ahead of the opening ceremony of the Paris Olympics.

The French state railway company SNCF called the overnight disruption a “massive attack aimed at paralyzing the high-speed line network.”

In a post on X, SNCF said that “a large number of trains were diverted or canceled,” and asked “all travelers who can to postpone their trip and not go to the station.”

The operator said the Atlantic, Northern and Eastern high-speed lines were impacted, with damage caused to several of its facilities, adding that one of the acts was “foiled” in the east after SNCF agents scared off several individuals.

SNCF CEO Jean-Pierre Farandou told journalists on Friday that cables – which are there to ensure the security of train drivers – were set on fire and taken apart but that authorities “don’t know who is behind it.”

Travel on the affected lines is “very disrupted,” with the railway network needing to divert and cancel a large number of trains, SNCF said. Disruptions – which it estimates could impact around 250,000 travelers today – were expected throughout the weekend, affecting 800,000 passengers, as work crews oversee repairs, it added.

The Rémi Train Centre Val de Loire said travel on its railway lines would be disrupted until at least Monday, with a fire near the tracks in Courtalain, northern France impacting services to Paris.

Farandou explained that they have to pull the damaged cables back together one by one, reconnect and test them. “It’s a question of security,” he said. “We have to make sure we test them so when trains are back up and running, they are safe.”

Brittany, a region in the northwest France, and the north of the country are the most impacted areas, SNCF said, though some trains have started running again, notably in eastern France. There would be no trains from Paris’ Gare Montparnasse, however, until at least 1 p.m. local time, Christophe Fanichet – the CEO of SNCF Voyageurs – told reporters.

Eurostar, the high-speed train service that connects the United Kingdom with France, has been forced to cancel and divert trains due to the “coordinated acts of malice,” on French lines.

The French Minister of Sports and the Olympic and Paralympic Games, Amélie Oudéa-Castera said the disruption to the train lines are “a sort of coordinated sabotage.”

Speaking BFMTV, Oudéa-Castera condemned the attacks in the “strongest possible terms,” and said it is “truly appalling.”

“We will assess the impacts on travelers, athletes, and ensure the proper transport of all delegations to the competition sites,” she said.

Other French officials echoed her description of the attacks being intentional. Outgoing French transport minister Patrice Vergriete and Valerie Pecresse, head of the Île-de-France region, in which Paris lies, said on Friday that “all elements” pointed towards it being a “deliberate attack.” Vergriete added those elements were “the coincidental timing, the vans found after the people had fled (and) the arson materials found on location.”

Outgoing French prime minister Gabriel Attal said in a post on X that the consequences are “massive and serious” while SNCF called the disruption an “attack on France.”

In response to the attacks, Paris police chief Laurent Nunez said Friday that police are stepping up security and focusing manpower on the capital’s train stations.

Security in Paris had already been bolstered in recent weeks.

The cause of the disruptions is currently unclear. But there has been growing domestic unrest, powered in part by recent national elections that saw a battle between the left and far-right.

Interior Minister Darmanin confirmed security forces had detained a “member of the extreme-right” this week who was “suspected of wanting to commit violent action during the Olympic Games.” According to Darmanin, the man had an “intention to intervene during a phase of the torch relay.”
