Furious anti-government youth dug in their heels in Iraq's capital and south on Sunday, rejecting the previous evening's nomination of Mohammad Allawi as premier after months of demonstrations and political paralysis.
Allawi was named prime minister-designate after a hard-won consensus among Iraq's rival parties, who had struggled to agree on a candidate since outgoing premier Adel Abdel Mahdi resigned under growing street pressure two months ago.
Mass rallies have rocked Baghdad and the mainly-Shiite south since October, with protesters demanding snap elections and an independent prime minister as well as accountability for corruption and recent bloodshed.
Young demonstrators have expressed contempt for the ruling elite and on Sunday, they slammed Allawi -- a former lawmaker and minister -- as part and parcel of the system they want to overhaul.
"Mohammad Allawi is rejected, by order of the people!" read a new sign hung in the holy city of Najaf on Sunday.
Young men with their faces wrapped in checkered scarves had spent the night torching car tyres in anger at Allawi's nomination and smouldering remains still blocked the main roads on Sunday, an AFP reporter there said.
In Diwaniyah, further south, protesters marched into government buildings to demand they close for the day while students began sit-ins at schools and universities. Protesters in Hillah blocked off all roads leading into the city and chanted, "Allawi is not the people's choice!"
