Presidential guard officers in Burkina Faso have announced the dissolution of the transitional government.
A new “national democratic council” has taken control, an officer said on state television.
Interim parliament speaker Cheriff Sy said the move was “clearly a coup”.
On Wednesday, the presidential guard arrested the interim president and prime minister. They were due to hand power to a new government after elections on 11 October.
Long-serving ruler Blaise Compaore was ousted in a popular uprising last year.
