Hundreds of followers of powerful Iraqi Shiite preacher Moqtada Sadr camped at the country's parliament Sunday for a second day, protesting against corruption and political mismanagement.

Despite tear gas, water cannon and baking temperatures that touched 47 degrees Celsius (116 degrees Fahrenheit), they stormed the complex on Saturday after pulling down heavy concrete barricades on roads leading to Baghdad's fortified Green Zone of diplomatic and government buildings.

The health ministry said at least 100 protesters and 25 security personnel were hurt in the confrontation.

Nearly 10 months after October elections, Iraq is still without a new government despite intense negotiations between factions.

Analysts have said Sadr, a mercurial cleric who once led a militia against US and Iraqi government forces, is using street protests to signal that his views must be taken into account in any government formation.

Both the United Nations and European Union warned about escalating tensions.

The immediate trigger for the occupation was the decision by a rival Shiite bloc, which is pro-Iran, to pick former cabinet minister Mohammed Shia al-Sudani for the prime minister's post.

"We were hoping for the best but we got the worst. The politicians currently in parliament have brought us nothing," said one of the protesters, Abdelwahab al-Jaafari, 45, a day labourer with nine children.

Volunteers distributed soup, hard-boiled eggs, bread and water to the protesters.

Some had spent the night inside the air-conditioned building -- which dates from dictator Saddam Hussein's era -- with blankets spread out on the marble floors.

Others took to the gardens, on plastic mats under palm trees.

Logjam

In multi-confessional and multi-ethnic Iraq, government formation has involved complex negotiations since a 2003 US-led invasion toppled Hussein.

Sadr's bloc emerged from elections in October as the biggest parliamentary faction, but still far short of a majority.

In June, his 73 lawmakers quit in a bid to break a logjam over the establishment of a new government.

The occupation that began on Saturday was the second time within a week that Sadr's supporters had forced their way into the legislative chamber.

They left on Sadr's orders last Wednesday after about two hours inside.

The protests are the latest challenge for a country trying to overcome decades of war and now facing the impact of climate change.

Despite oil wealth and elevated global crude prices, Iraq remains hobbled by corruption, unemployment and other woes, which sparked a youth-led protest movement in 2019.

As a result of past deals, the Sadrists also have representatives at the highest levels of government ministries and have been accused by their opponents of being as corrupt as other political forces.

But protesters see in Sadr an opposition figure and champion of the anti-corruption fight.

She accused Sadr's opponents of choosing for a new government figures "known for corruption".

Sudani is the prime ministerial choice of the Coordination Framework alliance which includes lawmakers from the party of Sadr's longtime foe, ex-prime minister Nuri al-Maliki.

It also represents the pro-Iran former paramilitary group Hashed al-Shaabi, now integrated into the regular forces.

On Sunday, a spokesperson for the European Union expressed concern about "the ongoing protests and their potential escalation".

The EU called for "constructive political dialogue".

Iraqi Kurdish authorities in the country's north offered to host talks in their capital Arbil.
