Following the June explosions on tankers in the Gulf of Oman, Iran was blamed. Limpet mines specific to Iran were given as MO https://www.foxnews.com/world/limpet-mine-oil-tanker-striking-resemblance-iranian-mines
The publicly available pieces of evidence for that seem to be 1) a magnet broken off something, found on a tanker, 2) a video of a Revolutionary Guard speed boat removing something from that (?) tanker, and 3) a picture of that tanker with something conical in shape, at some time previous to the video. 4) explosion damage
My points: The explosion damage looks more assymmetrical than the damage from other, confirmed, limpet mine attacks, and the general construction of such mines seems to not lend itself to anything but circular damage. Neither the shape, nor the method of attachment seem in any way specific to Iran.
Is there evidence for an Iranian limpet mine?
