Battles rage in southern Iraq

Mar. 27 - Fighting in Iraq's south between government-backed forces and Shi'ite militia continues for a third day.

Iraq's Prime Minister Nuri al-Maliki vowed security forces would battle Shi'ite militia in Basra "to the end" despite thousands of protesters marching to demand his resignation.

Mehdi Army fighters loyal to cleric Moqtada al-Sadr remain in control of streets of Basra, Iraq's second biggest city and main oil hub, defying a three-day government offensive that has led to violence spreading across the south and Baghdad.
