MIAMI (AP) — Two foreign-born men were charged in a federal complaint unsealed Monday with illegally providing U.S.-made parts to Iranian buyers for military aircraft, including fighter jets and attack helicopters.

Hassan Saied Keshari, 48, of Novato, Calif., and Traian Bujduveanu, 53, of Plantation, Fla., face between five and 20 years in prison if convicted of violating arms export laws and circumventing the U.S. embargo against Iran.

Prosecutors said Keshari, an Iranian who became a naturalized U.S. citizen, acted as the middleman between aircraft parts buyers in Iran and Bujduveanu, one of his suppliers. A Romanian by birth, Bujduveanu is also a naturalized U.S. citizen, they said.

"In essence, they are charged with helping Iran build up its military," said U.S. Attorney R. Alexander Acosta of Miami.

Neither had the proper U.S. license to export parts for aircraft such as the F-14 Tomcat fighter, the F-4 Phantom fighter, the C-130 cargo plane, the CH-53 helicopter and the AH-1 attack helicopter, prosecutors said.
