NextFin News - The 10-day-old conflict between Israel and Iran has entered a lethal new phase as the Israel Defense Forces (IDF) confirmed on Tuesday that Tehran is now deploying cluster munitions in its missile barrages. According to the Washington Post, these weapons—which scatter dozens of smaller "bomblets" over a wide area—have been detected in strikes across central Israel since March 5. The escalation follows a weekend of intense Israeli airstrikes on fuel depots in Tehran, marking the first time the IDF has targeted the Iranian capital’s energy infrastructure directly. In response, Iran has pivoted to these indiscriminate weapons to overwhelm Israel’s sophisticated air defense network, creating a "complicated and deadly challenge" for civilian protection efforts.
The shift in Iranian tactics represents a calculated attempt to bypass the Iron Dome and Arrow systems. While a single ballistic missile can be intercepted with high probability, a cluster munition that releases its submunitions mid-flight creates a saturation effect. Even if the primary carrier is destroyed, the resulting debris and unexploded bomblets pose a persistent threat to the ground. Data from the Alma Research and Education Center indicates that the intensity of these attacks peaked on March 9, with Hezbollah—Iran’s primary regional proxy—launching 31 waves of attacks in a single day, predominantly utilizing rockets and missiles to complement the Iranian long-range strikes. This coordinated effort aims to saturate Israeli defenses, forcing a choice between protecting high-value military assets or residential centers.
Legal experts are already sounding alarms over the humanitarian fallout. Unlike precision-guided munitions, cluster bombs are inherently indiscriminate. According to the Jerusalem Post, legal analysts suggest that the Iranian regime may be "deliberately targeting the Israeli civilian population" or, at the very least, conducting attacks with a reckless disregard for the distinction between military and civilian objectives. The danger is not merely immediate; cluster submunitions have a notorious "dud rate," meaning many do not explode on impact but remain active as de facto landmines. For a densely populated country like Israel, this creates a long-term internal security crisis that persists long after the sirens stop.
U.S. President Trump has maintained a posture of "maximum support" for Israel’s right to defend itself, though the introduction of cluster munitions by Iran complicates the diplomatic landscape. While neither the United States, Israel, nor Iran are signatories to the Convention on Cluster Munitions—the international treaty banning their use—the political optics of their deployment are severe. For Tehran, the use of these weapons is a signal of desperation and a lack of precision capabilities. For Israel, it provides a justification for further "decapitation strikes" against Iranian command and control centers. The strategic logic has shifted from containment to a war of attrition where the cost of failure is measured in civilian casualties.
The economic impact of this escalation is already being felt in global energy markets. As Israel targets Iranian fuel depots and Iran retaliates with weapons designed to maximize chaos, the risk of a total regional energy disruption has spiked. Market analysts note that the "cluster munition phase" of the war signals that neither side is currently seeking an off-ramp. Instead, the conflict is moving toward a total-war footing. The IDF’s focus has now shifted toward identifying and destroying the mobile launch platforms used for these cluster-capable missiles before they can reach the mid-flight deployment stage. As the war enters its second week, the technical arms race between Iranian saturation tactics and Israeli interception technology has become the defining feature of the Middle East’s most dangerous hour.
