Paris - Calls for greater gun control in the US have reached as far as the Eiffel Tower, where 100 demonstrators demanded "Protect children, not guns!"
The crowd at Saturday's gathering in Paris included American and French demonstrators, families and students.
Caitlin Waters, co-organiser of the March For Our Lives Paris gathering, says "it's important for Americans even overseas to make sure that Washington knows that we're not pleased with the gun control reform and we want more."
The march is one of hundreds across the US and the world to urge US lawmakers to pass stricter gun safety legislation after deadly school shootings.
It comes as France itself is shaken after four people were killed Friday in an extremist attack. Investigators are trying to determine how he got his weapon.
