Blaise Compaore, the president of Burkina Faso, has been forced to leave power after days of protests by tens of thousands of people calling for his ousting.
It appeared that the chief of the country's armed forces took power after the president's resignation.
Compaore announced his resignation in a statement on Friday and called for a 90-day transition to "free and transparent" elections in the West African country.
"I declare a vacancy of power with a view to allowing a transition that should finish with free and transparent elections in a maximum period of 90 days," said the statement, read on local radio and television by presenters.
