A potential coup is unfolding In Madagascar. An elite military unit, CAPSAT, has declared control of the armed forces and is demanding President Andry Rajoelina's resignation. This follows youth-led protests against the government. Yesterday, the armed forces minister recognized a military-backed officer as the new army chief. President Rajoelina has called the move an attempted coup. Meanwhile, South Africa has voiced deep concern over the unrest and is urging all parties to remain calm and respect Madagascar's democratic process.
