INDIANAPOLIS (AP): A former Indiana truck driver convicted of offering to assist Saddam Hussein's government in Iraq has asked a federal judge to set aside his 13-year sentence, but prosecutors say he should remain in prison.

Shaaban Shaaban was indicted in 2005 when he lived in the central Indiana city of Greenfield. He was convicted on charges he acted as a foreign agent for Iraq before the U.S. invasion in 2003. Prosecutors alleged he offered to sell Hussein's government the names of CIA operatives in Iraq and to coordinate human shields.

Federal prosecutors are opposing the 61-year-old Shaaban's petition for release from the federal supermax prison in Colorado, disputing his claims that the crimes were actually committed by a twin brother who later died.

Shaaban's attorney declined comment Friday.
