The protests in Basra started on Sunday, demanding jobs and better water and electricity services. Demonstrators have used burning tires to block roads.
Prime Minister Haider al-Abadi visited Basra on Friday, meeting local military and security officials, as well as the head of the Basra oil company.
He promised to “find new job opportunities.”
In the past week, protesters in Basra have blocked routes to oil fields, cut off access to the vital export centre Umm Qasr port, and threatened to shut down a border crossing with Iran.
Temperatures in southern Iraq can top 50 degrees Celsius in the summer. Sporadic electricity supplies and water shortages due to prolonged drought exacerbate the intense heat.
