DUBAI, United Arab Emirates (AP) — Airstrikes across Iran killed nearly three dozen people while Iran fired on Israel and Saudi Arabia, prompting the temporary closure of a major bridge. The latest strikes Tuesday came as Iranian officials urged youths to form human chains around power plants to protect them, as the latest deadline set by U.S. President Donald Trump to reopen the Strait of Hormuz drew closer. Trump has threatened to bomb all of Iran’s power plants and bridges if Iran does not meet his deadline to allow shipping traffic to fully resume through the strategic waterway. Israel’s military warned Iranians in Farsi to avoid taking trains throughout the day, likely telegraphing intended strikes on the rail network.
