Many others were wounded among the security forces, and it was feared the death toll could rise, said the official, Communications Minister Remy Danjuinou. Five emergency centers were set up in Ouagadougou to treat the high number of casualties in the former French colony.
It was not clear if more militants were involved in the violence, which was called a terrorist attack by Jean Bosco Kienou, director general of Burkina Faso’s police, and French Prime Minister Edouard Philippe. There was no claim of responsibility.
Gunfire and explosions resounded for hours but subsided by midday. Workers fled offices near the site of the violence, and helicopters were seen above the embassy.
Eight security personnel and eight attackers were killed in the fighting while 80 people including civilians, were wounded, officials say.
French Foreign Minister Jean-Yves le Drian said there was no doubt it was an act of terrorism.
