Live updates: Ceasefire disintegrates as US and Iran trade strikes over Strait of Hormuz

It’s been a volatile weekend in the Middle East. The flare-up between the US and Iran comes as both countries near the halfway mark of a 60-day window to negotiate the final terms of a deal, following an initial agreement in June.

What happened over the weekend:

As mediators race to revive diplomacy, Iranian Foreign Minister Abbas Araghchi travels to Muscat to meet with his Omani counterpart. Oman drafts a tentative proposal to manage traffic in the Strait of Hormuz through two separately controlled routes, according to a source.

Hours later, Iran’s Islamic Revolutionary Guard Corps (IRGC) say they fired a warning shot at a vessel trying to cross the Strait of Hormuz via an unauthorized route, and declares the waterway closed.

The US military launches its third round of strikes in a week, saying the IRGC “blatantly attacked” a Cyprus-flagged container ship transiting the Strait of Hormuz. Multiple explosions are reported in the south of Iran. In a later update, the US Central Command (CENTCOM) says it hit 140 Iranian military targets.

The IRGC says it launched strikes on US military targets across the Gulf. Authorities in Gulf nations report defending against attacks, including in Qatar, where three people are hurt by falling debris during interception operations.

Indian authorities say one of its nationals is missing after an attack on a commercial vessel on the Strait of Hormuz. It adds 10 others were rescued from the ship.

The US and Iran are at odds over the status of the Strait Hormuz. US President Donald Trump and CENTCOM insist the waterway is open, while Iran’s strait authority says the passage of vessels is “not possible.”

The US military launches another round of strikes after the previous day’s assault in the evening and says it hit dozens of Iranian military targets. Iran reports multiple explosions in the south of the country, including at a water pumping station where one person was killed.

Iran says it conducted a new wave of missile and drone attacks toward US bases in the region, including those in Kuwait and Bahrain.
