Timeline: Developments after Trump’s initial Hormuz deadline to Iran

A series of military escalations unfolded across the Middle East after US President Donald Trump issued an initial deadline to Iran to reopen the Strait of Hormuz, followed by repeated extensions and retaliatory strikes targeting key infrastructure and military assets. On March 21, Trump gave Iran 48 hours to reopen the strait, warning that US forces would strike the country’s energy facilities if it failed to comply. Two days later, on March 23, Trump said, "Very good and productive talks" had taken place, and postponed the planned strike by five days. On March 27, he extended the deadline further to April 6. Hostilities escalated on March 29, when a US E-3 Sentry early warning aircraft was damaged on the ground during an airstrike at Prince Sultan Air Base in Saudi Arabia.
