A Burundi army general says senior officers are “dismissing” President Pierre Nkurunziza, amid unrest over his bid to be re-elected to a third term.
Maj Gen Godefroid Niyombareh announced that a national salvation committee had been set up to run the country.
However, it is not clear how much support he and the other officers have.
President Nkurunziza is currently in Tanzania meeting other East African leaders to discuss the crisis. His aide dismissed the coup claims as “a joke”.
President Nkurunziza has rejected calls to postpone next month’s election.
Gen Niyombareh said he did not recognise the leadership because the president’s bid for a third term violated the constitution.
Soldiers have surrounded the offices of the national broadcaster.
The unrest began on 26 April and has led to the deaths of more than 20 people.
Tens of thousands of Burundians have fled to neighbouring states in recent weeks.
