MIAMI AP – A California man pleaded guilty Monday to conspiring to violate the U.S. embargo against Iran by arranging for the sale of parts for military aircraft, including fighter jets and attack helicopters.

Iranian-born Hassan Keshari, a 48-year-old naturalized U.S. citizen living in Novato, Calif., pleaded guilty to a single conspiracy count in a deal with prosecutors that could sharply reduce his prison sentence in return for continued cooperation. He faces a maximum of five years at sentencing set for April 8.
