Roadside bomb kills Iraqi governor.

A powerful roadside bomb on Saturday killed Khalil Jalil Hamza, the governor of the Qadisiyah province in southern Iraq, a province “that has seen fierce internal fighting between Shiite factions. … The area also has seen a rise in internal rivalries between rival militia forces, including the Mahdi Army that is loyal to radical Shiite cleric Muqtada al-Sadr.”
