US Strikes Iranian Sites as Ceasefire Between Washington and Tehran Collapses

US forces struck Iranian weapon launch sites, air defences, and coastal surveillance systems in the early hours of Wednesday, July 8, 2026. The operation came in response to Iranian attacks on three commercial vessels transiting the Strait of Hormuz the day before. The Guardian reported the operation was expected to "last for hours," according to US officials. Iranian state media reported explosions on the island of Qeshm and in the cities of Sirik and Bandar Abbas. Tehran immediately declared the ceasefire that has governed the conflict since April to be broken.

US Central Command labeled Iran's Tuesday attacks "unwarranted, dangerous, and a clear violation of the ceasefire," pointing to strikes on three tankers hit within hours of each other. The Al Rekayyat, a Qatari liquified natural gas (LNG) vessel—a ship designed to transport super-cooled gas—was struck while heading toward the Gulf of Oman The Guardian. A Saudi crude carrier, the Wedyan, was also damaged. Al Jazeera reported the LNG tanker risked exploding after being struck by a projectile.

Qatar's foreign ministry spokesperson, Majed al-Ansari, called the attack on the Al Rekayyat a "serious and explicit violation" of international law and said Qatar would hold Iran fully responsible. This response carries weight given Doha's role as mediator between Washington and Tehran throughout the ceasefire negotiations.

How the ceasefire framework came apart

The current truce dates to April 2026, followed in June by a memorandum of understanding (MOU)—a preliminary agreement—that launched 60 days of negotiations over Iran's nuclear program and a permanent end to hostilities. That MOU built on an earlier 14-point ceasefire framework and a two-week extension agreed May 28, pending then-President Trump's approval Reuters.

But the arrangement proved fragile almost immediately. CENTCOM records show strikes on June 9 in response to an attack on the USS Apache, additional strikes on June 26 after a cargo ship was hit, and more strikes on June 27 after another tanker was struck—followed by a halt to attacks and renewed talks that same day Reuters.

Technical talks in Doha concluded around July 1 aimed at restarting shipping through a corridor that handles roughly one-fifth of global oil shipments Reuters. CENTCOM also convened a regional security dialogue with 12 nations in Bahrain on the same day. Within a week, the framework those talks produced had unraveled.

The immediate trigger for Wednesday's strikes was the US Treasury's Tuesday revocation of a temporary sanctions waiver on Iranian oil exports, issued after the tanker attacks. Washington had lifted those sanctions following the June MOU; Iran's foreign ministry called their reimposition a breach of the memorandum and warned of "decisive measures." Washington gave Tehran until July 17 to wind down any oil transactions already underway Reuters.

Critics of the original sanctions waiver—including figures within the Trump administration itself—had argued it surrendered economic leverage before nuclear talks even began. That argument now looks prescient to some observers, premature to others, depending on where one stands in the sanctions debate.

The deeper dispute over the strait itself

Beneath the sanctions argument lies a more fundamental disagreement over who controls the Strait of Hormuz. Iran's Revolutionary Guard Corps has claimed since late June that the ceasefire gives Tehran authority over ship traffic through the waterway. The IRGC has issued passage warnings and boarded merchant vessels in the region. Oman, meanwhile, has proposed a new shipping corridor closer to its own coastline—a proposal Iran opposes, reportedly because Tehran wants the ability to charge vessels for use of the waterway.

Iran contends the MOU's language reserves management of the strait's reopening to Iran in consultation with Oman, and that US efforts to open alternative routes constitute a breach in themselves.

Experts point to the MOU's vague drafting as the structural problem. Both governments have been interpreting the same text to justify opposite behavior, and each incident becomes an occasion for mutual accusations of violation rather than a shared basis for de-escalation. That ambiguity may pose a more durable threat to the truce than any single military exchange.

The timing of Wednesday's strikes adds another layer. The operation fell during the days-long funeral for Iran's late Supreme Leader Ayatollah Ali Khamenei, a period in which Tehran's decision-making apparatus is occupied with succession as much as strategy. Iranian Foreign Minister Abbas Araghchi has condemned both the US and Israel over strikes he says violate the ceasefire, and Iran has signaled it will not return to talks unless Washington halts military action, according to Reuters reporting from July 7.

Whether the current exchange settles into another temporary halt—as happened after the June 27 strikes—or marks a further slide toward sustained conflict will likely depend on decisions made in Washington, Tehran, and Muscat over the coming days. It will also turn on whether either side is willing to accept a narrower, less ambiguous definition of what the ceasefire actually permits.
