US president calls on China, France, Japan and the UK to send vessels after US strikes Kharg Island oil facilities

• Middle East crisis – live updates

Iran threatened on Saturday to further escalate the war raging in the Middle East by targeting any facility in the region with US ties, after Donald Trump predicted “many countries” would send warships to support a US bid to reopen by force the strait of Hormuz, a critical waterway closed to virtually all maritime traffic by Tehran since the beginning of the war.

Iran has responded to the joint US-Israeli offensive, which is entering its third week, with daily attacks on oil and other infrastructure around the Gulf region, as well as against Israel.
