Iraq's oil exports are unaffected by the current political turmoil in the country, three sources told Reuters on Tuesday.
Baghdad is seeing its worst fighting for years as clashes between Shiite groups spill into a second day.
Supporters of Shiite cleric Moqtada al-Sadr have surrounded the Majnoon oil field in Basra since Monday evening as well as the 210,000 barrel per day (bpd) Basrah refinery, according to two sources.
But protesters are expected to leave these areas shortly after Sadr told supporters to withdraw from violent clashes, one of the sources said.
