A second military officer appears to have taken power in Burkina Faso, a third leader for the West African state in 24 hours.
Colonel Isaac Zida said he had assumed the powers of head of state, and called on the international community to recognise his authority.
Earlier, army chief General Honore Traore said he had taken over.
President Blaise Compaore stood down after 27 years in power amid political unrest on the streets of the capital.
He fled the country and has now arrived in Yamoussoukro, the capital of neighbouring Ivory Coast.
A violent Thursday saw protesters set fire to parliament and government buildings in the Burkinabe capital Ouagadougou.
At least three people were killed, though opposition leaders said dozens had died.
But on Friday crowds danced and cheered in the streets after Mr Compaore’s resignation was confirmed.
