In french.
In short :
Few hours before the opening ceremony of the olympics, 4 attacks occured on the 4 main high speed (300 km/h) rail highways.
Fire were set on strategical systems that paralysed 3 of the 4 lines. The last fire (south east line) was stoped before it damaged any critical system.
SNCF says it will probably take 2 or 3 days to repair the damaged. People are invited to postpone their travels. Rail is one of the most used transport mode in France and train stations In Paris are getting crowded as the police is beeing massively deployed in said stations.
Ministry of transport and ministry of interior (police) said they won't make any comment before further research.
