A former senior British military intelligence officer has told Sky News that the world could face huge economic turbulence, depending on how Iran chooses to respond to the US strikes.
Phillip Ingram says what happens next - with the Iranian leadership likely to feel compelled to respond - could be "really, really worrying".
He told Sky News presenter Matt Barbet earlier: "If Iran does shut the Straits of Hormuz, between 20 and 30% of all the world's oil and gas goes through that strait.
"The economic shock that would cause across the world would make what happened when Russia invaded Ukraine just over three years ago seem like small change."
Iran has other options, Ingram went on, with its proxies across the region.
Some of these, Ingram said, "were scary".
They range from terrorist activity to attacking US bases in the Middle East, he said.
