The department said it identified Muhsin al-Fadli and his deputy, Adel Radi Saqr al-Wahabi al-Harbi, as Iranian-based facilitators and financiers for al-Qaida. A collective reward of up to $12 million was offered for information about the men.
"Both men are wanted by Saudi authorities in connection with their terrorist activities, and al-Fadhli is wanted by authorities in Kuwait on terrorism-related charges," the U.S. Justice Department said in a statement.
The department added that Fadhli had advance knowledge of the Sept. 11, 2001, attacks on the United States. Harbi, for his part, is alleged to have helped al-Qaida militants travel through Iran from Iraq and Afghanistan.
Both men were sanctioned by the Treasury Department for their role as al-Qaida operators in Iran. The department added that it believed regional al-Qaida networks tied to both men were fighting in the Syrian civil war.
David Cohen, U.S. undersecretary for terrorism and financial intelligence, said the action exposes al-Qaida's foundation in Iran.
"We will continue targeting this crucial source of al-Qaida's funding and support, as well as highlight Iran's ongoing complicity in this network's operation," he said in a statement.
