French soldier Cedric Cordier was in hospital in a stable condition after yesterday's stabbing in a busy underground shopping and transport hub where he had been on patrol with two colleagues.
French President Francois Hollande said the stabbing could not be linked to the London murder "at this stage", although his interior minister, Manuel Valls, said the "sudden violence of the attack" was similar.
The assault on another soldier three days after Afghanistan veteran Drummer Lee Rigby was hacked to death on a London street in an Islamist attack will raise fears of a spiral of brazen violence against Western soldiers on their home soil.
