BBC: France's high-speed TGV rail network has been damaged by a "concerted campaign of sabotage", the SNCF state-owned rail operator has said.
It said acts of sabotage overnight, including fires, caused huge delays to TGV services already hit by a long transport union strike over reforms.
The SNCF blamed militants for the attacks, saying they wanted to harm ongoing talks to end the strike.
President Nicolas Sarkozy said the saboteurs would be severely punished. French trains 'hit by sabotage' (more)
