This must have made the mullahs steaming mad. From USA Today:

    The United States blocked an Iranian cargo plane’s flight to Syria last month after intelligence analysts concluded, using satellite photos, that it was carrying sophisticated missiles and launchers to resupply Hezbollah in southern Lebanon, two U.S. intelligence officials say.

    Eight days after Hezbollah’s war with Israel began, U.S. diplomats persuaded Turkey and Iraq to deny the plane permission to cross their territory to Damascus.

    The episode was detailed by one U.S. intelligence official who saw a report on the incident. It was confirmed by a U.S. official from a second intelligence agency and by a diplomat with a foreign government.
