An army commander who led a mutiny in Madagascar said on Tuesday the military had taken power after President Andry Rajoelina was impeached by lawmakers and forced to flee the country following weeks of youth-led protests.

Rajoelina had refused to step down despite escalating Gen Z demonstrations demanding his resignation and widespread defections in the army.

"We have taken the power," Colonel Michael Randrianirina declared on national radio and said that the military was dissolving all institutions except the lower house of parliament or National Assembly.
