CNN reports that "Saddam Hussein was hanged Saturday for crimes committed in a brutal crackdown during his reign, U.S. and Iraqi sources tell CNN. Iraq's national security adviser said: 'He was a broken man... You could see fear in his face.' President Bush called the execution 'an important milestone' for Iraq".
The execution took place shortly after 6am local time (2pm Sydney Time). Just 5 minutes before that time (13:57:45), I sent a short message to my Iraqi friend, saying "Saddam is going to be executed in FIVE minutes!"
The time could be reasonably speculated.
