Prosecutors in Georgia say two Americans were at the center of a complex plot to illegally ship aircraft parts to the Iranian military.

Prosecutors said Thursday that the two Americans have pleaded guilty to conspiring to illegally export fighter jet and attack helicopter parts from the U.S. to Iran. Five other people based in France, the United Arab Emirates and Iran have been charged with helping.

An indictment says the companies purchased parts from a firm run by Michael Todd, of Macon. The indictment also says Hamid Seifi of Chicago purchased aircraft parts from Todd on behalf of a company in Iran. The supplies were funneled to Iran through the French company.

Seifi has been sentenced to more than 4 years in prison. Todd's sentencing is scheduled for August.
