France is on high alert after the beheading of a teacher this month by an 18-year-old Muslim man.
French school teacher Samuel Paty was beheaded in a Paris suburb after showing his students Mohammed cartoons during a lesson on freedom of expression.
President Emmanuel Macron vowed that the country "will not give up cartoons" as he was vilified by protesters in Bangladesh, Pakistan, Syria, Gaza Strip and Libya.
Meanwhile, the French government has urged its citizens to be cautious in countries that have announced the boycott of French products after Turkish President Erdogan backed calls to boycott French goods.
"In several countries in recent days, there have been calls for a boycott of French products, particularly foodstuff, and more generally calls to protest against France," the French foreign ministry said.
"It is advisable to avoid areas where demonstrations are held, to stay away from gatherings, and to follow the guidance of the relevant French embassy or consulate," it added.
"It is recommended to be most vigilant, especially when travelling, and in places frequented by tourists and expatriate communities," the French government said.
