As Operation Epic Fury enters its 36th day, the US-Israeli war on Iran has dramatically widened — with strikes hitting Iran’s petrochemical infrastructure, a fresh Israeli bombing campaign in Beirut, a desperate search for a missing American airman, and Iran firing cluster munitions at central Israel.
Saturday, April 4, 2026, has brought some of the most significant developments yet in the five-week conflict, with the war now touching nuclear facilities, petrochemical complexes, multiple capital cities, and the Strait of Hormuz — the world’s most critical oil chokepoint.
Petrochemical Plants Ablaze in Khuzestan Province
In one of the most consequential escalations of the war, US and Israeli forces struck two major petrochemical facilities in Iran’s southwestern Khuzestan province on Saturday morning. The Mahshahr Special Petrochemical Zone — one of Iran’s largest industrial complexes — was hit in coordinated airstrikes, according to the deputy governor of Khuzestan Province, Valiollah Hayati.
Iran’s Mehr news agency confirmed that the state-run Bandar Imam petrochemical complex, which produces chemicals, liquefied petroleum gas (LPG), polymers, and a range of other industrial products, also sustained significant damage. The strikes represent a major escalation in the coalition’s targeting strategy, moving beyond military and nuclear sites to directly attack Iran’s economic infrastructure.
The petrochemical sector is a critical pillar of Iran’s economy, generating billions in annual revenue. Targeting these facilities signals that the US and Israel are now willing to wage economic warfare alongside their military campaign — a dramatic shift that could have far-reaching consequences for global energy and chemical supply chains.
Bushehr Nuclear Plant Hit Again — One Killed
Adding to the day’s developments, a projectile struck the perimeter of the Bushehr Nuclear Power Plant, killing at least one person, according to Iranian state media and the International Atomic Energy Agency (IAEA). This marks the second time the Bushehr facility has been targeted during the conflict.
The IAEA has expressed grave concern about strikes near active nuclear facilities, warning of potential radiological consequences. Bushehr is Iran’s only operational nuclear power plant, built with Russian assistance and connected to the national grid. Any significant damage to the reactor could trigger a radiological emergency with regional implications.
Israel Launches Massive Strikes on Tehran and Beirut Simultaneously
In a dramatic display of multi-front capability, the Israeli Air Force launched a heavy wave of airstrikes targeting both Tehran and Beirut simultaneously early Saturday morning. Multiple explosions shook the Iranian capital, with the Israeli military saying it targeted “Iranian regime infrastructure sites.”
In Beirut, the IDF announced it had begun striking “Hezbollah infrastructure” in the Lebanese capital after destroying a bridge in eastern Lebanon to prevent the Iran-backed militia’s reinforcements from crossing into the country. An AFP journalist on the ground reported at least two loud explosions in Beirut within half an hour, with smoke billowing from the southern suburbs — a stronghold of Hezbollah that has been repeatedly targeted since Israel’s ground invasion of southern Lebanon.
The simultaneous strikes on two capital cities underscore the breadth of the conflict, which has expanded far beyond Iran’s borders. Israel is now fighting on multiple fronts — hitting Iranian targets deep inside the country while simultaneously conducting operations in Lebanon.
Iran Fires Cluster Munitions at Central Israel
Iran’s response has been equally fierce. On Saturday, Iranian forces launched ballistic missiles carrying cluster bomb warheads at central Israel, striking the city of Ramat Gan near Tel Aviv. Magen David Adom (Israel’s emergency medical service) reported treating a 52-year-old man who was lightly injured by the blast, with submunitions scattered over a wide area.
The use of cluster munitions — banned by more than 100 countries under the Convention on Cluster Munitions (though neither Iran, Israel, nor the US are signatories) — represents a dangerous escalation in the type of weaponry being deployed. Cluster bombs scatter smaller bomblets over a wide area, posing a severe risk to civilians long after the initial attack.
Iran has launched over 20 missiles targeting Israel in recent days, and the IDF confirmed that Tehran fired multiple salvoes — including a 10-missile barrage that was among the largest single attacks since the war began on February 28.
Missing American Airman: A Race Against Time
The search for a missing US airman has entered its second day, creating a tense standoff that carries enormous military and diplomatic stakes. The F-15E Strike Eagle — the first American warplane shot down by Iran in the five-week conflict — went down over southwestern Iran on Friday.
One of the two crew members has been rescued, but the fate of the second remains unknown. Iranian Revolutionary Guard Corps forces are also searching the crash area, raising fears that the missing American could be captured and used as political leverage against the United States.
In a notable gesture, an Israeli official told the New York Times that Israel has suspended attacks on Iran in the area where the airman is believed to have been lost, and is sharing intelligence with American forces to aid the search. A US Black Hawk helicopter involved in the rescue effort was hit by ground fire on Friday but managed to escape safely.
President Trump stated that the missing airman would not affect efforts to reach an agreement with Iran to end the war, telling NBC News the conflict was likely to continue for weeks.
Three US Carrier Strike Groups Now Deployed
The scale of US military commitment to Operation Epic Fury continues to grow. According to the Atlantic Council’s military asset tracker, three US Navy Carrier Strike Groups are now deployed in the region, along with two Amphibious Ready Groups carrying Marine Expeditionary Units. The operation has now exceeded 10,000 combat flights and struck over 10,000 Iranian targets, according to US Central Command.
The Air Force has deployed every type of operational fighter, bomber, and aerial tanker in its inventory — including B-2 stealth bombers, B-1 Lancers, and B-52 Stratofortresses — along with cargo, ISR, electronic warfare, and battle management aircraft. The sheer scale of the air campaign has prompted analysts to warn about long-term impacts on US military readiness in other theaters, particularly the Pacific.
Strait of Hormuz: Ships Trickle Through as Oil Tops $109
The Strait of Hormuz remains effectively shut by Iran’s naval blockade, though some vessels continue to trickle through with Iranian permission. Turkey’s transport minister confirmed that a second Turkish-owned ship passed through the strait, with efforts underway to extract the remaining nine Turkish vessels trapped in the waterway.
A French-owned CMA CGM container ship is believed to be the first Western-flagged vessel to make safe passage since the war began. However, the vast majority of shipping through the strait — which normally carries a fifth of the world’s oil supply — remains blocked.
Brent crude surged nearly 8% on Friday to approximately $109 per barrel, with the energy crisis triggered by the conflict now being described as the worst since the 1970s oil embargo. The war has also pushed up global prices for gas, fertilizer, and basic goods, with economic pain spreading far beyond the Middle East.
NATO in Crisis Over the War
The geopolitical fallout continues to mount. Reuters reported that the US-Israeli war with Iran has nearly broken the 76-year-old NATO alliance, leaving it in its weakest state since its creation. European allies have largely refused to participate in or endorse the military campaign, creating deep fissures with Washington at a time when the alliance was already strained over Ukraine and Trump’s past threats regarding Greenland.
The death toll continues to rise across the region. In Gulf nations, at least 50 people have been killed in attacks attributed to Iran, including strikes on Kuwait’s largest oil refinery that set multiple units ablaze. In Israel, at least 17 people have died. The American military death toll stands at 13 service members, with hundreds wounded. Iranian civilian casualties from US and Israeli strikes are believed to be significantly higher, though exact figures remain difficult to verify.
What Comes Next
As Week 6 of Operation Epic Fury looms, the conflict shows no sign of winding down. Trump’s threat to target power and desalination plants by next week if Iran doesn’t reopen the Strait of Hormuz sets the stage for an even more devastating phase of the war. Iran’s leadership has shown no sign of capitulating, and its missile capabilities — while degraded — remain potent enough to threaten Israel, Gulf states, and coalition forces.
The missing American airman, the expansion to petrochemical targets, and Iran’s use of cluster munitions all point toward an intensifying conflict that is reshaping the Middle East — and the global order — in real time.
