An explosion jolted Burkina Faso's army headquarters in the capital Ouagadougou and black smoke can be seen billowing above, Reuters reported.
A "terrorist attack" hit Burkina Faso's capital Ouagadougou, France's ambassador to West Africa's Sahel region said after an explosion rocked the army headquarters there and witnesses reported seeing masked gunmen attack the building.
It was not immediately clear what caused the blast but witnesses said they heard gunfire before the explosion and that the building was on fire.
An armed attack is underway in downtown Ouagadougou near the prime minister's office and UN roundabout, the Burkina Faso Police said.
They added that security units have been deployed to the scene and have urged people to stay away from the area.
According to witnesses, five armed men got out of a car and opened fire on passersby before heading towards French embassy. Others said there was an explosion near the Burkinabe military headquarters.
Meanwhile, the French Embassy in Burkina Faso announced that it is under attack and is asking people to stay in their homes.
