French train network hit by 'malicious' attacks before Olympics ceremony, rail firm says

A series of fires have hit French high-speed rail lines, hours before the Paris Olympics opening ceremony.

Rail company SNCF said it is a "massive attack aimed at paralysing the network" and France's transport minister condemned the "co-ordinated malicious acts".

Some 800,000 customers are affected with disruption expected all weekend, the rail firm said
