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.
