In oil-rich Basra, the southern port city where the protests broke out on July 8, tribal chiefs and Shiite religious leaders joined several hundred demonstrators in front of the provincial headquarters.

Security forces were deployed en masse as demonstrators railed against chronic power cuts, water shortages and endemic unemployment, along with state incompetence and foreign interference.

While there were no clashes over the weekend, fourteen people have been killed since the unrest flared, including at least one person shot dead by security forces.

In Samawa, further west, protestors have been staging a sit-in for more than a week, condemning the misappropriation of billions of dollars from the state budget over recent years.

Daily demonstrations have continued despite government pledges to pump billions of dollars into oil-rich but neglected south.

But the initially large protests have dwindled, apparently weakened by numerous arrests and a heavy security presence.

Anti-corruption rallies have also hit Baghdad's central Tahrir Square, but they too have waned to just a few dozen protestors.

Prime Minster Haider al-Abadi on July 29 sacked Electricity Minister Qassem al-Fahdawi, whose departure had been demanded by demonstrators.

Fahdawi's dismissal came amid political tensions as Iraq awaits the results of a partial recount of May 12 elections.
