The prime minister of Iraq today ordered an investigation into the conduct of Saddam Hussein’s execution in a bid to learn who in the group of witnesses taunted the former Iraqi leader in the last minutes of his life and leaked a mobile-phone video of his death to an Arab satellite television station and website.

Sunni Muslims, angered by the execution of Saddam Hussein and the hurried and undignified way his hanging was carried out, have taken to the streets of Iraq in mainly peaceful demonstrations.

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 northern Iraq today, killing at least 22 people and wounding 26, police said.

Funeral processions began today for the people who were killed by car bombs and mortars in Baghdad’s largest Shiite district, the deadliest attack since the war began.
