I'd assume, until further evidence, it's because the Strait is an active war zone.

Fair point, but the IRGC telling ships to turn around, as opposed to the ships themselves doing it (as per reporting) would imply that the Strait has been blockaded in some fashion. It remains to be seen if this is all a bluff, I'm just as skeptical as this would be their last option, but given the strikes on other Gulf countries, the threat seems a bit more plausible of actually being real.

That regime has absolutely nothing to lose at this point and they will use whatever they've got.
