US Iran News LIVE: The fragile detente between Washington and Tehran suffered a major setback this Saturday, April 18, as Iran officially rescinded its decision to reopen the Strait of Hormuz. The Iranian joint military command announced that the world’s most vital oil artery is back under “strict management,” effectively resuming a blockade in retaliation for President Donald Trump’s refusal to lift the US naval siege on Iranian ports.

The escalation comes despite a whirlwind of high-stakes diplomacy. Pakistan’s Army Chief, Field Marshal Syed Asim Munir, has just concluded a critical mission to Tehran, attempting to broker a settlement before the current ceasefire expires on April 22. While President Trump teased “pretty good news” and suggested a deal is within reach, his insistence that the blockade remains in “full force” until a “100% complete transaction” is reached has drawn a fierce rebuke from Iranian leadership.

As the 10-day truce between Israel and Hezbollah enters its second day, the region remains on a knife-edge. With the Strait of Hormuz closed once more and the US-Iran ceasefire ticking toward its Tuesday deadline, the stakes for next week’s scheduled talks in Islamabad could not be higher.

Iran-US war ceasefire: Key developments

  1. Hormuz lockdown: Iran’s military warns transit will remain blocked as long as the US blockade of Iranian ports continues, reversing a brief opening earlier this week.
  2. Trump’s ‘transaction’: Speaking aboard Air Force One, the President stated he will not ease naval pressure until Tehran yields on demands, including its nuclear programme.
  3. Pakistan’s mediation: Field Marshal Asim Munir met with President Masoud Pezeshkian; Islamabad is now preparing to host a second round of direct US-Iran talks.
  4. Ghalibaf’s warning: Iran’s Parliament Speaker dismissed Trump’s optimism, labeling several US claims “false” and reaffirming Iran’s defensive posture.
  5. The 10-day window: While a ceasefire holds in Lebanon, Hezbollah warns its “hands remain on the trigger” as the IDF maintains positions in the south.
