The warning was delivered through a flurry of ‌high-level diplomatic contacts after President Donald Trump threatened on July 28 to strike Iran’s energy network and infrastructure, the sources said. Two senior Iranian officials, two Gulf sources and a senior regional diplomat with knowledge of the discussions said Iranian Foreign Minister Abbas Araqchi spoke with his Saudi, Turkish and Qatari counterparts, as well as Pakistan’s army chief. Araqchi urged Washington’s Gulf allies to use their influence ​with Trump to dissuade him from launching renewed strikes, the senior diplomat said, warning that any attack on Iran would prompt retaliation against US assets and energy facilities across the ​Gulf. “The Iranian warning was unequivocal: if America targeted Iran’s infrastructure, they would retaliate by striking Gulf energy facilities and other regional targets,” one Gulf source said. Saudi Crown Prince Mohammed bin Salman subsequently spoke with Trump, urging him to delay military action, return to negotiations, secure a ceasefire and pursue a diplomatic settlement, the senior diplomat and Gulf sources said.
