A Reuters witness said that heavy gunfire was heard from the main army camp in Ouagadougou (the capital of Burkina Faso) early Sunday morning.
The shooting at the Sangoli Lamizana camp, which houses the army’s chief of staff, began as early as at least 5 a.m. local time and was still audible until 6:30.
A government spokesman said he also heard the shooting and was seeking information about the matter.
Authorities arrested at least 8 soldiers earlier this month on suspicion of plotting against the government.
The shooting comes a day after clashes erupted between security forces and demonstrators who defied a ban on gathering to protest the lack of security.
Riot police dispersed the demonstrators using tear gas, and chased some protesters through the streets of the center of the capital, where young men could be seen on motorbikes trying to harass the police.
The protesters set up barricades of wood, stones and burning tires in several places.
Since 2015, Burkina Faso has witnessed a cycle of violence attributed to armed groups linked to al-Qaeda and the Islamic State.
Demonstrations or attempts to gather were also recorded in other cities in Burkina Faso.
Attacks targeting civilians and military personnel increased, mostly concentrated in the north and east of the country.
