Saddam Hussein's chief deputy, who has eluded capture since the U.S.-led invasion of Iraq three years ago, purportedly called for Arab leaders to back Iraq's Sunni-backed insurgency, in an audiotape broadcast Monday.
The tape, which Al-Jazeera television said was made by Izzat Ibrahim al-Douri, appeared to be an address to the Arab League summit in Khartoum, Sudan, this week.
The voice on the tape said Iraq's Sunni-led insurgency was "the sole legitimate representative of the Iraqi people."
Al-Douri was sixth on the U.S. deck of cards that enumerated the most-wanted members of Saddam's regime. He had been Revolutionary Command Council vice chairman and a longtime Saddam confidant.
It was impossible to determine the tape's authenticity.
