Death toll rises during violent clashes between rival Shia groups after Muqtada al-Sadr resigns from politics

Explainer: why are Shia groups fighting each other in Iraq?

Supporters of the powerful Iraqi cleric Muqtada al-Sadr have heeded his call to return to their homes after a day of clashes that left at least 30 people dead, wounded hundreds and sparked fears of a wider conflict within the country’s Shia population.

Raising hopes that the immediate crisis would ebb, Sadr on Tuesday called for the Iraqi army to retake control of Baghdad’s green zone, which had been the scene of the fiercest fighting between Sadrist members and pro-Iranian militias. Shortly after noon, the city’s streets were rapidly emptying, as Iraq’s prime minister praised a stand-down that many observers believe helped avert a descent into protracted violence.
