Could Iraq be on the brink of civil war? Protesters in Baghdad have expressed outrage after Wednesday's storming of an anti-government rally in the holy city of Najaf by supporters of populist cleric Moqtada al-Sadr. It could be a turning point in the four-month uprising against a power-sharing system demonstrators say has made politicians unaccountable, with corruption and mismanagement unchecked. To find out how it's impacted the movement, FRANCE 24 went to southern Iraq. Senior reporter Cyril Payen, who was there, joins The Debate panel to discuss the future of the movement.
