Iranian Cluster Munitions Strike Israeli Residential District as Crude Hits 18-Year High

Ramat Gan attack marks escalation to direct civilian targeting while Hormuz closure drives Dated Brent above $141, highest since 2008.

Iranian cluster munitions struck residential areas of Ramat Gan in central Israel on April 4, wounding at least four civilians and damaging multiple buildings—the latest in a documented pattern of attacks on population centers as crude oil surged past $140 per barrel amid the ongoing Strait of Hormuz blockade.

The attack spread submunitions across a wide area, collapsing at least one building and igniting vehicles in Ramat Gan, Bnei Brak, Givatayim, Petah Tikva, and Rosh Ha’ayin, according to Times of Israel. A 52-year-old blast victim was among the wounded. The incident follows three confirmed cluster munition strikes in March that killed 13 Israeli civilians, including two deaths in Ramat Gan on March 18.

Human Rights Watch documented Iran’s use of cluster munitions in at least four attacks on Israeli civilian areas since March 1. The weapons release dozens of submunitions designed to disperse over wide areas—a characteristic that makes them indiscriminate when used in populated zones. According to the Arms Control Association’s executive director, “Iran appears to be launching them into relatively populated areas, probably with the goal of producing potential civilian harm.”

Energy Markets Under Dual Pressure

The strike comes as Oil Markets face unprecedented disruption from Iran’s de facto closure of the Strait of Hormuz, now in its 31st day. Physical crude prices spiked to levels not seen since 2008, with Dated Brent climbing above $141 per barrel on April 2, per Bloomberg. Futures contracts traded at $109.03 for June delivery as of April 4.

The Hormuz closure affects approximately 20% of global oil supply—roughly 20 million barrels per day under normal operations, per Al Jazeera citing US Energy Information Administration data. Since March 4, when the Islamic Revolutionary Guard Corps issued warnings prohibiting vessel passage, tanker traffic through the strait has dropped to near-zero.

“With the conflict now expected to last at least into deep April, the barrel math becomes increasingly grim. Nearly 1 billion barrels will be lost by the end of the month.”

Goldman Sachs estimated a $14 per barrel geopolitical risk premium as of March 3, noting that a full one-month Hormuz closure could add $15 per barrel with no supply offsets. That forecast has proven conservative—the actual premium embedded in physical markets now exceeds $30 per barrel relative to pre-conflict levels.

Trump’s 48-Hour Ultimatum

President Trump escalated military threats on April 3, warning Iran that “48 hours before all Hell will reign down on them” if the strait remains closed, reported CNBC. “We will consider when Hormuz Strait is open, free, and clear,” Trump stated. “Until then, we are blasting Iran into oblivion or, as they say, back to the Stone Ages.”

The ultimatum, delivered via social media, marks the third deadline Trump has announced since the conflict began February 28 with US-Israeli strikes that killed Supreme Leader Ali Khamenei. Previous warnings failed to achieve Iranian compliance. US military planners have reportedly identified Iranian bridges, power plants, and port facilities as potential targets, though the administration has offered no clear framework for how infrastructure destruction would compel strait reopening.

Civilian Toll Mounts

At least 22 Israeli civilians have been killed and over 6,594 injured in Iranian ballistic missile and cluster munition attacks since February 28. The April 4 Ramat Gan incident marks the fifth confirmed cluster munition strike on Israeli population centers, continuing a pattern that Human Rights Watch characterised as deliberate targeting of civilian infrastructure.

Previous incidents include nine deaths in Beit Shemesh on March 1 and two construction workers killed in Yehud on March 9. The March 18 Ramat Gan attack killed two residents in their 70s who were found outside designated safe rooms. Today’s strike hit the same municipality, suggesting either persistent targeting or limited precision in Iranian strike planning.

Cluster Munitions

Cluster munitions release dozens to hundreds of smaller submunitions over a wide area. When used in populated areas, they are inherently indiscriminate and violate international humanitarian law prohibiting attacks that fail to distinguish between military and civilian targets. Over 100 countries have banned their use under the 2008 Convention on Cluster Munitions; neither Iran nor Israel are signatories.

Cross-Market Contagion

Energy market stress is radiating across asset classes. Equity markets showed heightened volatility following Trump’s latest threats, with particular weakness in transport and manufacturing sectors sensitive to fuel costs. European refiners face acute pressure as alternative supply routes from the Middle East require longer tanker journeys around Africa, adding 12-15 days transit time and corresponding freight premiums.

The conflict’s duration is now the critical variable in price forecasting. Goldman’s initial analysis assumed a two-week disruption; the strait has now been effectively closed for a month with no clear reopening mechanism. Ryan McKay of TD Securities noted that extending the blockade through April would result in cumulative supply losses approaching 1 billion barrels—a scale that would exhaust strategic reserves and force demand destruction in developing economies.

What to Watch

Trump’s 48-hour deadline expires midday April 5. Market participants are pricing three scenarios: Iranian compliance and strait reopening (low probability, would trigger sharp crude sell-off); US infrastructure strikes without Iranian capitulation (high probability, oil sustains above $130); or Iranian counter-escalation targeting Gulf state energy facilities (tail risk, could push Brent toward $200).

The intersection of civilian casualties from cluster munitions and energy market disruption creates dual escalation pressure. Israel has historically responded to civilian deaths with expanded military operations, while oil above $140 imposes direct economic costs on US consumers—gasoline futures are tracking toward $5 per gallon nationally. Whether Trump’s infrastructure threat represents genuine intent or negotiating posture will become clear within 24 hours. Iranian willingness to absorb further strikes while maintaining the Hormuz closure suggests the conflict has entered a war of attrition phase where neither side has identified an acceptable off-ramp.
