Rage over the hanging of Saddam Hussein spilled into the streets in many parts of the Sunni Muslim heartland today, especially in Samarra where a mob of angry protesters broke the locks off the badly damaged Shiite Golden Dome mosque and marched through carrying a mock coffin and photo of the executed former leader.

A car bomb exploded in a Shiite holy city and 13 members of one Shiite family were gunned down north-east of the capital today in a surge of attacks that killed at least 30 people despite heightened security aimed at curbing sectarian violence following the bombing of a revered Shiite shrine.

Iraq’s most influential Shiite political leader today called for Sunni-Shiite unity as religious figures sought to calm passions and pull the nation from the brink of civil war after the bombing of a Shiite shrine two days ago and a wave of deadly reprisal attacks.
