Opposition parties and civic groups in Burkina Faso have called a mass rally for Sunday in protest at the army takeover after the resignation of President Blaise Compaore, reports GHN based on BBC.
They said the management of the transition belonged to the people and should not be confiscated by the army.
It came hours after the army said Lt-Col Isaac Zida, second-in-command of the presidential guard, had been chosen as the nation's transitional leader.
Mr Compaore has fled to Ivory Coast.
"The victory born from this popular uprising belongs to the people, and the task of managing the transition falls by right to the people," opposition groups said in a statement.
"In no case can it be confiscated by the army."
There were protests earlier this week after Mr Compaore sought to amend the constitution and extend his long hold on the presidency.
On Thursday, protesters set fire to parliament and government buildings in the capital Ouagadougou.
