The governments of Burkina Faso and France said an armed group coordinated attacks Friday on France's embassy and cultural center and on the West African country's military headquarters in the capital.

At least seven soldiers were killed in the attacks and the government officials said eight other militants were slain. More than 90 people were wounded in the violence in the former French colony in West Africa and officials called it a terrorist attack.

There has been no claim of responsibility.

Five emergency centers were set up in hospitals, a military barracks and at a stadium in Ouagadougou to treat the casualties.

Gunfire and explosions resounded for hours but subsided by midday.

There are fears that the death toll could rise.

White House spokeswoman Sarah Sanders made the allegation Thursday after President Vladimir Putin announced an array of new nuclear weapons.
