Supporters of the influential Shia cleric Muqtada al-Sadr have vowed to continue their occupation of the Iraqi parliament for a second day as the country's political crisis continues to deepen.
Hundreds of demonstrators on Saturday stormed the parliament building for the second time in four days, with scores of protesters and police reported injured.
Nearly 10 months after October elections, Iraq is still without a new government despite intense negotiations between factions.
The immediate trigger for the occupation was the decision by a rival Shia bloc, which is pro-Iran, to pick former cabinet minister Mohammed Shia al-Sudani for the prime minister's post.
Waving Iraqi flags and flags that represent Sadr's party, demonstrators, some of whom threw stones, battled through tear gas and water cannons to force their way into the legislative chamber.
Earlier, demonstrators had pulled down heavy concrete barricades on roads leading to Baghdad's fortified Green Zone of diplomatic and government buildings.
