The United States launched airstrikes against Iran following an Iranian attack on a Cyprus-flagged container ship in the Strait of Hormuz, which caused significant damage and left one crew member missing. In response to the US strikes, Iran retaliated by targeting several countries in the Middle East, including Bahrain, Kuwait, Qatar, Oman, and Jordan, which host US military forces. Iran's paramilitary Revolutionary Guard also declared the Strait of Hormuz closed "until further notice" after striking the vessel, further escalating tensions. US Central Command confirmed hitting approximately 140 targets in Iran, including missile and drone sites, and affirmed that the Strait of Hormuz remains open to lawful transit, with US forces prepared to ensure freedom of navigation.

This escalation profoundly threatens ongoing efforts to secure a permanent end to a war that began on February 28. The Strait of Hormuz, a critical transit route for approximately one-fifth of global oil and natural gas supplies before the war, has been a key point of contention. Iran's actions to close the strait have already led to a global energy crisis, though oil prices have since decreased from wartime highs of $120 a barrel. The US is demanding that Iran publicly commit to ceasing attacks on ships in the strait and ensure all shipping lanes are open without tolls.

Despite the renewed violence, mediators, including Pakistan, Qatar, and Egypt, are continuing efforts to maintain an interim ceasefire agreement reached on June 17, which was intended to last 60 days. Oman, where Iranian and Omani foreign ministers discussed mechanisms for safe passage through the strait on Saturday, also played a mediating role. The US president, Donald Trump, had initially declared the interim deal "over," but talks are reportedly continuing at technical and political levels between Oman and Iran to address the strait's status.
