A series of coordinated arson attacks targeting France's high-speed rail network caused widespread disruption on the eve of the Paris Olympics opening ceremony.

The attacks resulted in the cancellation of numerous train services across the country.  

French authorities have launched a criminal investigation into the incidents, which involved burning crucial fiber-optic cables along several TGV lines. The railway operator, SNCF, described the attacks as a "massive attack" aimed at paralyzing the network.  

While no group has claimed responsibility, security sources suggest the method used is similar to those employed by extremist groups in the past. However, there is no concrete evidence linking any specific group to the attacks.  

The French government has condemned the acts as criminal and vowed to bring those responsible to justice. Despite the disruptions, authorities maintain that the Olympic opening ceremony will proceed as planned.  

The attacks have caused significant inconvenience for travelers, with many forced to cancel or postpone their journeys. (ILKHA)
