What evidence is there of this? I was under the impression that Khobar was a Bin Laden Special. Do you have a link to an article connecting Iran to that?

Attorney General John Ashcroft has assured the relatives of the 19 U.S. servicemen killed in the bombing of Khobar Towers that justice will be done. But the indictment issued Thursday for the bombing suggests that even if the U.S. managed to round up any of the accused, the resulting trial would be about as satisfying to the victims' loved ones as the Lockerbie trial was to the families of those killed in the bombing of Pan Am 103. Two Libyan intelligence agents were tried for that crime, but nobody doubted that the real author — there are not too many individuals in Libya with the authority to order an outrage of such profound international consequences — was never in court.
The indicted men are mostly Saudi members of the Iran-backed Hezbollah guerrilla movement, and the indictment alleges that unnamed Iranian officials "inspired, supported and supervised" the accused men in their surveillance activities preceding the attack. And it doesn't take an intelligence analyst to figure out that an organization "supported and supervised" by Iran would not attack the world's most powerful military in a traditionally hostile neighboring country unless someone pretty powerful in Tehran had signed off on the strike.
