Madagascar police Saturday used tear gas to break up a rally by supporters of ex-president Marc Ravalomanana, who was placed under house arrest after returning from exile in South Africa. The former president, who was sentenced in absentia to life imprisonment with hard labour, slipped back into Madagascar on October 13, five years after a military coup and two months of violent protests forced him to flee first to Swaziland and then to South Africa.
