An army captain in Burkina Faso, Ibrahim Traore, has announced that he has ousted military leader Lt Col Paul-Henri Damiba.
The dismissal of Lieutenant-Colonel Damiba, who came to power in a coup last January, was announced in a statement read out on national television.
The rebelling military also announced the closure of borders from midnight, as well as the suspension of the constitution and the dissolution of the government.
Traore cited Lt Col Damiba’s inability to deal with an Islamist insurgency as the reason for the coup.
But his administration has also not been able to quell the jihadist violence. On Monday, 11 soldiers were killed when they were escorting a convoy of civilian vehicles in the north of the country.
Earlier on Friday, Lt Col Damiba urged the population to remain calm after heavy gunfire was heard in parts of the capital.
More than 20 armed soldiers – most with their faces covered – appeared on state TV shortly before 20:00 local time.
“Faced with the deteriorating situation, we tried several times to get Damiba to refocus the transition on the security question,” said the statement signed by Traore.
“Damiba’s actions gradually convinced us that his ambitions were diverting away from what we set out to do. We decided this day to remove Damiba,” it said.
A curfew from 21:00 to 05:00 was also announced.
Lt Col Damiba’s whereabouts are not known.
The United States said it was “deeply concerned” by events in Burkina Faso and encouraged its citizens to limit movements in the country.
