It is now confirmed Iran did the attacks from Iranian soil. There are videos posted by Iranians that show them going out, 12 total. All of them hit where aimed, and the targets were annihilated.

Iran is not taking credit for this but I think it is pretty obvious when two days ago the Mossad took out two Iranian officers in Syria. The Pentagon and Israel are claiming no damage and no fatalities but we know both are unabashed liars.
