Some Arab sources report that an explosion was heard in Jordan, Fars reports; several explosions were heard from American bases in Jordan

The sourcing here matters: initial reports via Fars, an Iranian state-linked outlet, are worth treating as a signal of Iranian framing as much as of fact, and past episodes of this kind have been subject to conflicting early accounts before official confirmation. The prior sequence in comparable episodes has run from initial strike, to casualty assessment, to a calibrated US response, with the market-relevant variable being whether American personnel are killed or wounded, since that threshold has historically been the trigger for retaliation and a broader risk move. The transmission channel on confirmation has typically run through crude, via supply-risk premium on any widening toward direct US-Iran confrontation, and through haven demand in gold, Treasuries and the dollar, with equities fading on escalation headlines and recovering when responses prove contained. Worth watching is confirmation from US officials or regional wire services, casualty reporting, and any attribution language from Washington, which in past cycles has telegraphed the scale of the follow-on response.
