The French embassy and a French cultural center are under attack in Burkina Faso's capital, Ouagadougou, Friday.
Witnesses told the French news agency AFP that five armed men got out of a car and opened fire on passersby before heading to the embassy.
An AFP reporter heard an exchange of heavy gunfire and saw a vehicle on fire which witnesses said was used by the gunmen.
A message posted on Facebook by the embassy said: "Attack under way at the French embassy and French Institute. Stay indoors."
There has been no immediate claim of responsibility for the attack.
