French government spokesman Olivier Veran says Paris condemns the coup in Gabon and wants the election result to be respected.
Earlier, Prime Minister Elisabeth Borne said France is following events in Gabon “with the greatest attention”.
On Monday, President Emmanuel Macron denounced what he called an “epidemic” of coups in recent years in French-speaking Africa, from Mali and Burkina Faso to Guinea and most recently Niger.
Paris maintains a military presence in many of its former colonial territories, including Gabon, where it has 370 soldiers permanently deployed, some in the capital, Libreville, according to the French Ministry of the Armed Forces website.
