AP is reporting the following:

Iraqi authorities reported the arrests Wednesday of two guards and an official who supervised Saddam Hussein's hanging and said the guard force was infiltrated by outsiders who taunted the former leader and shot the video showing his body dangling at the end of a rope.

The unauthorized video, which ignited protests by Saddam's fellow Sunni Arabs in various Iraqi cities, threatens to turn the ousted dictator into a martyr. Saddam was shown never bowing his head as he faced death, and asking the hecklers if they were acting in a manly way.

National Security Adviser Mowaffak al-Rubaie and two other top officials variously reported one to three men were being questioned in the investigation into who heckled Saddam as he was minutes from death and took cell phone pictures of his execution.

"The investigation has already had an arrest warrant against one person and two to follow," al-Rubaie told CNN. He said the guard force at the execution was infiltrated by an Arab television station or another outsider.

The clandestine footage appeared on Al-Jazeera television and Web sites just hours after Saddam was hanged Saturday. The tumultuous scenes quickly overshadowed an official execution video, which was mute and showed none of the uproar among those on the floor of the chamber below the gallows.
