Stun grenades and tear gas are used on groups of demonstrators in Madagascar's capital, Antananarivo, on the twelfth day of a protest movement that has plunged the country into an acute political crisis. "This is a revolution," says Iando Rakotondrina, one of the protesters. "We're just looking for justice, a good leader for Madagascar because we're in free fall," says Ezechiel, another protester.
