ANTANANARIVO (Reuters) -Madagascar's President Andry Rajoelina said on Tuesday he had dissolved the lower house of parliament, escalating a standoff with youth-led protesters and the military that forced him to flee the island. A presidency decree on Facebook said the 51-year-old Rajoelina had consulted with the leaders of the National Assembly and the upper house Senate, but the legality of his gambit was unclear. In a defiant address from an undisclosed location on Monday evening, Rajoelina refused to step down despite weeks of Gen Z protests demanding his resignation and widespread defections in the army.
