Several hundred Shi'ite demonstrators have rallied in central Baghdad to call for reforms.
The protesters gathered at Tahrir Square on April 17, chanting, "Yes, yes to Iraq; no, no to corruption."
The rally comes after powerful Shi'ite cleric Muqtada al-Sadr threatened to call mass protests if lawmakers failed to vote in "a cabinet of independent technocrats" by April 19.
Last month, Sadr organized a two-week sit-in in March outside Baghdad's heavily fortified Green Zone, where the government is headquartered.
Iraq has been hit by weeks of political turmoil surrounding Prime Minister Haidar al-Abadi's efforts to replace the cabinet of party-affiliated ministers with a government of technocrats.
Abadi has said the turmoil could threaten the campaign against the Islamic State group, which controls large swathes of territory in the country's north and west.
