Iran attacks UAE, strikes US ships as Hormuz ceasefire shatters
Confidence: HIGH (78/100) | May 04, 2026 | Tehran, Tehran, Iran
aljazeera.com
In one sentence: Iran fired missiles and drones at UAE targets and US Navy ships in the Strait of Hormuz on May 4, as the US military forced two American-flagged merchant vessels through the contested waterway.
Why it matters: The April 8 ceasefire is breaking down in real time: Iran resumed strikes on UAE territory for the first time since early April while directly contesting US military passage through the Strait of Hormuz. With roughly 20% of global oil trade transiting the strait, the renewed fighting threatens to lock in near-$125 oil prices and could force a return to full-scale hostilities between the US-Israel coalition and Iran — now on Day 66 of a war that has already killed thousands and displaced millions across the Middle East.
What Happened Today
- Iran launched missiles and drones at the United Arab Emirates on May 4, with UAE air defenses issuing three missile alerts — the first since the April 8 ceasefire — and authorities in the eastern emirate of Fujairah reporting an Iranian drone had sparked a fire at an oil facility, according to NPR and Al Jazeera.
- The US military destroyed six small Iranian boats in the Strait of Hormuz on May 4 after Iran launched 'multiple cruise missiles, drones and small boats' at US Navy ships and commercial vessels, CENTCOM Commander Admiral Bradley Cooper told reporters, adding Apache and SH-60 Seahawk helicopters carried out the attacks.
- Iran's state media claimed two missiles struck a US Navy vessel near the strait; CENTCOM flatly denied any US ship was hit, calling the claim baseless, and said two American-flagged merchant ships had successfully transited the waterway.
- Iranian Armed Forces Commander Maj. Gen. Ali Abdollahi issued a direct warning on state broadcaster IRIB: 'We warn that any foreign military force — especially the aggressive U.S. military — that intends to approach or enter the Strait of Hormuz will be targeted.'
- The US-led Joint Maritime Information Center established an 'enhanced security area' south of standard shipping lanes in Oman's waters, urging mariners to coordinate with Omani authorities, while the US has warned shipping companies they could face sanctions for paying Iran transit fees.
Contested Claims
- Iranian state media (Fars News Agency / IRIB): Two missiles struck a US Navy vessel near the Strait of Hormuz after it ignored Iranian navy warnings to halt. US Central Command (CENTCOM), Admiral Bradley Cooper: No US vessel was struck; Iran's claim is 'baseless.' Two US-flagged merchant ships successfully transited the strait.
- Iranian state media: Iran's navy prevented US ships from entering the Strait of Hormuz. US Central Command (CENTCOM): Two American-flagged merchant ships have transited the Strait of Hormuz without incident.

Frequently Asked Questions
Is the Iran-US ceasefire over? The April 8 ceasefire is under severe strain. Iran resumed drone and missile strikes on the UAE on May 4, and US forces destroyed six Iranian boats in the Strait of Hormuz. Trump told Congress the ceasefire had 'terminated' hostilities, but then said publicly 'we're in a war.' No formal end to the ceasefire has been declared by either side.
How is the Strait of Hormuz closure affecting oil prices and shipping? Iran's effective closure of the strait, through which roughly 20% of global oil trade passes, has driven Brent crude to near $125 per barrel. The US blockade has denied Iran roughly $5 billion in oil revenue and left 31 Iranian tankers with 53 million barrels stranded in the Gulf, according to the Pentagon.
What happens next in the Iran war? CENTCOM Commander Admiral Cooper briefed Trump on potential next-phase options including limited ground interventions and energy infrastructure strikes, per GlobalSecurity.org. Diplomatic talks via Pakistan remain technically open but stalled on Iran's right to enrich uranium. CSIS analysts assess Iran is waging a war of endurance, using Hormuz leverage to outlast US political will.
Background
The 2026 Iran war began on February 28, 2026, when the US and Israel launched joint strikes on Iran — dubbed Operation Epic Fury — targeting military sites, missile infrastructure, and Iranian leadership, including Supreme Leader Ali Khamenei, who was killed. Iran retaliated with hundreds of missiles and drones across the Middle East and closed the Strait of Hormuz; a US-mediated ceasefire was declared April 8 but nuclear talks in Islamabad collapsed without agreement, and the ceasefire began unraveling in early May as the US pushed to reopen the strait by force.
