Dozens of Iraqi protesters stormed on Thursday Umm al-Qasr commodities port as this led to the disruption of work in the port.
protesters are demanding better services, said port employees and local
government officials, raising the stakes in some of the worst unrest in
southern cities in months.
The move came hours after protesters set fire to the main government building in the oil hub of Basra.
Basra and the surrounding province have been the focus of angry demonstrations over government neglect that have rocked Iraq since early July.
Residents are particularly angry over pollution of the local water supply, which has put 20,000 people in hospital.
