Arabic television channel Al Arabiya has aired an audio tape it said was from ousted Iraqi leader Saddam Hussein in which he demanded the United States unconditionally withdraw its forces from Iraq.
The speaker on the tape also urged Iraqis to intensify attacks against US forces and to "wage holy war by all means against the foolish invaders".
Addressing the United States, the voice on the poor quality recording said: "We call on you to withdraw your forces as soon as possible, and without any conditions, as you can not bear any more losses as these losses will be catastrophic for you."
"Your withdrawal from our country is inevitable, whether it happens today or tomorrow, and tomorrow will come soon."
The voice also told Iraqis not to become complacent with the occupation, adding: "O Iraqis! O fighters, men and women, you must tighten the noose around the Americans and increase your attacks against them. You must conduct jihad by all means possible, financial and otherwise."
The speaker gave the date of the recording as September.
Arab channels have in the past aired several recordings purportedly made by Saddam who was ousted in the US invasion of Iraq in April. The Iraqi leaders' whereabouts remain unknown.
An audio tape purportedly from Saddam, aired on September 1st, denied he had any part in postwar Iraq's bloodiest bombing which killed a top Shi'ite Muslim cleric and more than 80 others. But he also urged more attacks on the occupiers.
