Iranian Cluster Munitions Strike Central Israel, Injuring 15

On Sunday, March 22, an Iranian ballistic missile carrying a cluster warhead dispersed bomblets across Tel Aviv and nearby cities in central Israel, injuring 15 people — one of them seriously [1]. The attack was the fourth Iranian ballistic missile salvo since midnight, part of a conflict now in its 23rd day that has killed thousands across the region and sent global oil prices past $90 a barrel [2][3].

Seven of the wounded were taken to Tel Aviv Sourasky Medical Center (Ichilov Hospital), four in moderate condition [1]. The Magen David Adom ambulance service reported that the most serious injuries were sustained by a 53-year-old man [1]. Damage was reported to homes and roads across multiple impact sites in Tel Aviv and Petah Tikva, with one missile striking the third story of a residential building, causing its partial collapse [4].

Israeli air defenses engaged the incoming projectiles but failed to intercept them [1] — a recurring problem that has defined this war's most distinctive tactical challenge.

The Weapon: Anatomy of Iran's Cluster Warheads

Iran's cluster-equipped ballistic missiles work by splitting open at approximately 7 kilometers altitude, releasing dozens of small explosive submunitions — called bomblets — that scatter across roughly 8 kilometers of terrain below [5]. Each bomblet weighs between 2.5 and 7 kilograms [5].

Most Iranian ballistic missiles carry approximately 24 bomblets per warhead, though the Khorramshahr missile — one of Iran's most capable systems — can carry up to 80 [6][7]. Several missile families in Iran's arsenal, including the Khorramshahr, Emad, and Ghadr series, have versions configured for cluster payloads [5].

An IDF spokesman told The Wall Street Journal that Iran has employed cluster munitions "almost on a daily basis" since the war began [6]. By March 10, Israel stated that roughly 50 percent of all ballistic missiles fired at the country during the conflict carried cluster warheads [6]. A Haaretz investigation on March 12 reported that 11 Iranian cluster missiles had penetrated Israeli air defenses, with one single missile dropping 70 bomblets over central Israel [8].

The shift toward cluster warheads represents a tactical calculation. Conventional unitary warheads can be destroyed by interceptor missiles; cluster bomblets, once released at altitude, scatter across too wide an area for point-defense systems to address [7][9].

The Targeting Question: Residential Areas and Military Proximity

The March 22 bomblets struck across Tel Aviv, Jaffa, and Petah Tikva — predominantly residential and commercial areas [1][4]. Haaretz reported six separate impact sites across the Tel Aviv metropolitan area [4].

The Arms Control Association's executive director characterized Iran's targeting of cluster warheads at residential neighborhoods as deliberate [4]. Col. (res.) Dr. Liron Libman, former head of the IDF's International Law Division, argued that Iran may be "deliberately targeting the Israeli civilian population" or conducting "indiscriminate attacks," given that the weapons lack the precision required for military objectives [10].

Iranian state media has consistently framed its strikes as responses to specific Israeli actions. Saturday's strikes against Dimona and Arad — which wounded at least 180 people — were presented as a "response" to an Israeli attack on Iran's Natanz nuclear enrichment complex earlier that day [3]. The broader campaign is framed as retaliation for the US-Israeli strikes that killed Supreme Leader Ali Khamenei on February 27 and the subsequent bombing campaign [2][11].

Whether specific military installations were located near the March 22 impact sites remains contested. Israel does not publicly disclose all military facility locations in its urban centers, and Iran has not specified what targets it intended to strike in the Tel Aviv area.

Forensic Identification and Verification

Israeli military assessments have identified the weapons as Iranian-manufactured based on missile debris analysis and the pattern of bomblet dispersal [6]. CNN conducted independent analysis of two separate Iranian cluster munitions attacks, confirming multiple impacts spread across areas of seven and eight miles respectively, with bomblets falling on homes, businesses, roads, and parks at random [7].

The Washington Post reported that the submunitions recovered from Israeli soil match known Iranian designs, though comprehensive independent international verification — such as by the United Nations or the Organisation for the Prohibition of Chemical Weapons — has not been publicly released as of this writing [12]. The pace of ongoing conflict has limited the capacity for third-party forensic investigation.

The Unexploded Ordnance Crisis

Cluster munitions are distinctive among weapons for the long-term hazard they create. Bomblets that fail to detonate on impact remain embedded in soil, pavement, and rubble, functioning as de facto landmines that can kill or maim civilians for years or decades after a conflict ends [13].

Failure rates vary significantly between manufacturer claims and field conditions. While manufacturers claim rates as low as 0.01%, the Israeli Winograd Commission — investigating Israel's own use of cluster munitions in Lebanon in 2006 — found actual field failure rates of 12–18% for artillery-delivered systems and approximately 5% for rocket-launched variants [10]. The UN estimated that 30–40% of cluster munitions used by Israel in Lebanon failed to explode [14].

Iran's ballistic-missile-delivered bomblets have not been subject to published independent failure rate testing. If failure rates approximate even the lower end of historical ranges — 5% — a single Khorramshahr missile carrying 80 bomblets would leave an estimated four unexploded devices scattered across civilian areas. With cluster munitions used on a near-daily basis over more than three weeks of conflict, the cumulative unexploded ordnance burden across Israel is mounting rapidly.

The Casualty Count in Context

The 15 injuries from the March 22 strike, while individually significant, are part of a larger pattern. The conflict's deadliest cluster munitions attack on Israeli soil occurred on March 1, when an Iranian ballistic missile strike on Beit Shemesh killed nine people and injured more than 20 [6]. Two workers were killed and a third seriously injured in Yehud, outside Tel Aviv, after being struck by submunitions from another cluster-equipped missile [6].

As of March 21, at least 18 people have been killed in Israel since the war began [2]. This figure stands in stark contrast to casualties in Iran, where figures vary widely by source: Iran's government reported 1,444 dead including at least 204 children [11]; the NGO HRANA documented 3,114 deaths by March 17, including 1,354 civilians [15]; and the Hengaw Organization for Human Rights counted at least 5,300 killed in the war's first 18 days [15].

Regional casualties extend further — at least 1,001 killed in Lebanon since Israel renewed attacks there, and fatalities in Bahrain, Kuwait, and Oman from Iranian strikes on Gulf state targets [2][11].

Iran's Escalating Direct Strikes: A Historical Pattern

Prior to 2026, Iran directly struck Israeli territory twice — both times in 2024 [16][17].

In April 2024, Iran launched a combined drone, cruise missile, and ballistic missile attack in response to Israel's bombing of an Iranian consulate complex in Damascus. Despite the scale of the operation, casualties were minimal: five missiles hit Nevatim Air Base, but no Israeli deaths resulted [16].

In October 2024, Iran launched approximately 200 ballistic missiles in two waves, responding to the killings of Hamas leader Ismail Haniyeh and Hezbollah leader Hassan Nasrallah. Roughly 32 missiles struck Nevatim airbase. One Israeli civilian died from a stress-related heart attack; two others were lightly injured [17].

The 2026 conflict represents a qualitative escalation. Iran's shift from targeting military airbases with conventional warheads to striking urban areas with cluster munitions marks a fundamental change in both method and apparent intent. The cumulative toll of at least 18 Israeli dead and hundreds injured far exceeds the combined impact of both 2024 attacks.

International Law: Neither Side Has Clean Hands

Neither Israel nor Iran is a signatory to the 2008 Convention on Cluster Munitions (CCM), which prohibits the use, production, transfer, and stockpiling of cluster weapons [13][18]. The treaty has been ratified by 112 states but is notably absent the signatures of the United States, Russia, China, India, Israel, Iran, Pakistan, and Brazil [13].

Col. (res.) Dr. Liron Libman emphasized that "customary international law does not prohibit the use of cluster munitions per se" [10]. Legality instead hinges on two principles: distinction (the requirement to differentiate between civilian and military targets) and proportionality (balancing military advantage against civilian harm) [10].

Israel's own record with cluster munitions is extensive and contested. During the 2006 Lebanon War, the IDF fired an estimated 4 million submunitions into south Lebanon, with Human Rights Watch documenting that "the vast majority" were launched in the final three days of the conflict, when a ceasefire was already imminent [14]. HRW's investigation across more than 40 towns concluded that Israel's use was "both indiscriminate and disproportionate, in violation of international humanitarian law, and in some locations possibly a war crime" [14].

The IDF's internal inquiry exonerated the armed forces but never released its detailed findings or supporting evidence, making independent assessment impossible [14]. The Winograd Commission documented unexploded ordnance in Lebanese villages despite orders prohibiting fire into inhabited areas, citing "lack of clarity in orders" and disciplinary failures [10].

Israel also faces an ongoing International Criminal Court investigation into its military operations in Gaza. Palestinian representatives raised concerns over "Israeli use of internationally banned weapons in its attacks on the Gaza Strip" at a Convention on Cluster Munitions meeting in September 2024 [18]. Evidence documented by Truthout and The Canary indicated Israeli cluster munitions use in Lebanon as recently as 2025 [19].

When asked about this record, Israeli officials have consistently distinguished between weapons used against military targets embedded among civilian populations and Iran's alleged deliberate targeting of civilian neighborhoods. Critics counter that this distinction is difficult to maintain when the weapons themselves — by design — cannot discriminate between combatants and non-combatants once dispersed.

The Oil Price Shock

The conflict's economic impact extends far beyond the immediate combatants. Iran's attacks on oil infrastructure in the Persian Gulf — including vessels in the Strait of Hormuz, through which 20% of the world's oil transits — have triggered fuel shortages in parts of Asia and sharp global price increases [2].

WTI crude oil prices rose from approximately $67 per barrel in late February to above $98 by mid-March, a spike of roughly 46% in under three weeks [20]. Israeli strikes on Iran's South Pars gas field have further compounded the energy market disruption [21].

What Comes Next

On March 21, an Israeli military official identified as "Zamir" stated that the campaign against Iran was at the "halfway" stage [22]. Iran's targeting of Dimona — home to Israel's main nuclear research facility — and Israel's strike on Natanz have introduced nuclear dimensions to the escalation cycle [3].

The cluster munitions question is unlikely to recede. Each day of conflict adds unexploded bomblets to Israeli soil — devices that will need to be located, mapped, and cleared in a process that took Lebanon years after 2006 and is still incomplete. For the 15 people injured in Tel Aviv on March 22, and for the communities living among scattered bomblets that may or may not detonate at an accidental touch, the war's consequences will persist long after the last missile is fired.
