U.S. President Donald Trump and Israel on Saturday (April 4, 2026) stepped up pressure on Iran to open the strategic Strait of Hormuz or face attacks on its energy infrastructure, ‌while Iranian and U.S. forces searched for a missing U.S. crew member from one of two downed warplanes. In an ‌apparent move to heap further pressure on Tehran following Trump’s latest ultimatum, a senior Israeli defence official said Israel was preparing to attack Iranian energy facilities, and was awaiting approval from the U.S. The timeframe for such attacks would be within the next week, the official said.
