French President Emmanuel Macron has warned against "stigmatising" Muslims or linking the Islamic religion with the fight against terrorism.
"We have to stand together with all our fellow citizens," Mr Macron said during a joint press conference with German Chancellor Angela Merkel on Wednesday.
It came as a French woman said she was taking legal action against far-right politicians who criticised her for wearing an Islamic headscarf in public.
France has about five million Muslims.
It is the largest Muslim minority in Western Europe.
Wearing the Muslim headscarf or veil - known as a hijab - is banned in French schools, government offices and some other public buildings.
France is officially a secular state and body-covering garments have been at the centre of a number of controversies in recent years. [BBC] Read more
