Burkina Faso state TV is currently off-air, BBC Monitoring confirms, amid heavy gunfire in the capital Ouagadougou.
There are soldiers along the main avenue leading to the presidency, and some areas near buildings around the national radio have been restricted.
Burkina Faso saw a military coup in January this year, with Colonel Paul-Henri Sandaogo Damiba seizing power.
On Thursday, hundreds of demonstrators took to the streets in the western Burkina Faso city of Bobo Dioulasso to demand his resignation.
The protesters reportedly blamed Damiba for the chaotic management of the security situation.
Tension in Burkina Faso comes days after deadly attack
The situation in Burkina Faso is confusing and it’s unclear who is behind the deployment of soldiers in the capital, Ouagadougou, and around the presidential palace.
Gunfire has also been reported at military barracks.
It is however notable that bodies of 11 soldiers and 50 civilians were discovered on Monday in the northern town of Djibo after an ambush on Monday.
The military, led by Lt Col Paul-Henri Sandaogo Damiba, took power in a January coup, promising an end to the Islamist insurgency that started in 2015, but violence still rages.
