Tunisian President Kais Saeid has dismissed the head of the national television station, Mohamed Lassaad Dahech, and appointed a provisional replacement.
Earlier Mr Saeid sacked a large number of senior government officials.
He assumed executive and judicial powers at the weekend after suspending parliament and removing the prime minister.
The president's opponents have accused him of staging a coup.
But he insists that he acted within his powers at a time of crisis.
Tunisia is beset by a crippled economy and surging Covid infections, causing growing international concern.
