Shafaq News/ The Commander-in-Chief of the Iraqi Armed Forces, Prime Minister Mustafa al-Kadhimi, headed an emergency meeting with senior security commanders to discuss the ongoing tension inside Baghdad's heavily fortified Green Zone.

According to a readout issued by his bureau, al-Kadhimi urged the demonstrators to immediately evacuate the Green Zone to avoid hampering the social peace.

The Prime Minister instructed the security forces to pursue utmost caution when dealing with the protestors and protect public and private properties.

Earlier today, al-Sadr said he was quitting politics and closing his institutions in response to an intractable political deadlock, sparking protests by his followers and raising fears of more instability.

Al-Sadr's supporters, who have been staging a weeks-long sit-in in Baghdad's fortified Green Zone, a sprawling area of ministries and foreign missions, stormed the main cabinet headquarters and demonstrated inside after his announcement. 

Iraq's Joint Operations Command (JOC) declared a curfew from 3:30 p.m. (Iraq time) and urged the protesters to leave the Green Zone to avoid clashes.

During the stalemate over forming a new government, al-Sadr has galvanised his legions of backers, throwing into disarray Iraq's effort to recover from decades of conflict and sanctions and its bid to tackle sectarian strife and rampant corruption.

Al-Sadr was the biggest winner from an October election but withdrew all his lawmakers from parliament in June after he failed to form a government that excluded his rivals, mostly Iran-backed Shiite parties.

Al-Sadr has insisted on early elections and the dissolution of parliament. He says no politician who has been in power since the U.S. invasion in 2003 can hold office.

"I hereby announce my final withdrawal," al-Sadr said in a statement posted on Twitter, criticising fellow Shiite political leaders for failing to heed his calls for reform.

He did not elaborate on the closure of his offices, but said that cultural and religious institutions would remain open.

Al-Sadr has withdrawn from politics or government in the past and also disbanded militias loyal to him. But he retains widespread influence over state institutions and controls a paramilitary group with thousands of members.

He has often returned to political activity after similar announcements, although the current political deadlock in Iraq appears harder to resolve than previous periods of dysfunction.

The current impasse between al-Sadr and Shiite rivals in the Coordination Framework has given Iraq its longest run without a government.

Supporters of the mercurial cleric then stormed Baghdad's central government zone. Since then, they have occupied parliament, halting the process to choose a new president and prime minister.

Iraq has struggled to recover since the defeat of Islamic State in 2017 because political parties have squabbled over power and the vast oil wealth possessed by Iraq, OPEC's second-largest producer.
