A soldier has been stabbed in the throat in the French commercial district of La Defense outside Paris.
The stabbing came just days after British soldier Lee Rigby was hacked to death on a London street in broad daylight in a suspected terrorist attack that has raised fears of potential copycat strikes.
However, there was no immediate confirmation of any link to Saturday's attack in France.
Military spokesman Colonel Thierry Burkhard said the French soldier was wounded but that his life was not in danger.
French authorities are investigating any possible links with the Woolwich attack but president Francois Hollande said the identity of the attacker was unknown and cautioned against jumping to conclusions about the assault on the uniformed 23-year-old soldier.
"There could be a link, but we will look at all the elements," Mr Hollande said during a news conference in Ethiopia, where he was travelling.
