Trump threatens Iranian infrastructure after Houthis block Red Sea artery | 21 July 2026 | U.S. President Donald Trump vowed on Wednesday to destroy an Iranian bridge or power plant every time Iran ​shoots at a ship in the Strait of Hormuz, raising the stakes after Iranian-allied Houthis in Yemen threatened a second vital energy route. Five tankers changed course in the Red Sea to avoid the ‌Bab el-Mandeb Strait on Wednesday, a day after the Houthi threat to block Saudi oil exports highlighted a new risk to global oil supplies from the escalating conflict. Three tankers loaded with Saudi oil for China and India made U-turns on Tuesday. Iran’s joint military command warned, according to state media, that if Trump’s threat against infrastructure was carried out, Iranian forces would target regional oil, gas, electricity and economic infrastructure and prevent the export of “even a single drop of oil.”
