France has said a "reaction with force" could be needed if Syria is proved to have used chemical weapons against its own people.
The comments from Foreign Minister Laurent Fabius come as Syrian activists say hundreds of people were killed in such attacks in Damascus on Wednesday.
The UN has asked Syria to allow UN weapons inspectors already in the country to be allowed to investigate.
There is no sign as yet that Damascus will allow this.
