Israel says Iran is using cluster munitions. What to know about the weaponsIsrael has accused Iran of deploying cluster munitions during the ongoing conflict between the two nations, raising alarm about the humanitarian risks and military challenges posed by the controversial weapons. According to Israeli officials, Iran has launched missiles carrying cluster warheads throughout the ten-day war, creating a complex threat for Israel’s already stretched air defense systems and increasing dangers for civilians on the ground.
Cluster munitions are weapons designed to disperse dozens of smaller explosives over a wide area after being released from a larger missile or bomb. Once the main warhead opens in the air, it scatters multiple smaller submunitions—commonly known as bomblets—across a large radius. These bomblets can explode on impact, but many fail to detonate immediately, remaining on the ground as unexploded hazards that can injure or kill civilians long after the fighting ends.
Israeli authorities have recently begun publicly warning citizens about these weapons, explaining the risks they pose and urging people to avoid touching unexploded objects. The warnings come after several casualties were reported in central Israel, where unexploded submunitions have already caused deaths and injuries.
The accusations against Iran highlight not only the tactical implications of cluster munitions in modern warfare but also the ongoing global debate about their legality and humanitarian impact.
What Are Cluster Munitions?
Cluster munitions are a category of explosive weapons designed to release multiple smaller bombs over a large area. Instead of a single explosion, these weapons distribute many smaller explosives that can strike targets across several hundred meters or even several kilometers.
- Typically, a cluster munition is launched as a missile, rocket, artillery shell, or dropped from an aircraft. At a certain altitude—often between seven and ten kilometers—the main container opens and disperses dozens of submunitions. These bomblets fall to the ground and detonate upon impact.
- The design allows military forces to cover large areas quickly, making cluster munitions effective against dispersed targets such as troop formations, vehicles, or air defense systems.
- However, critics argue that this wide-area coverage comes at the cost of precision. Because the bomblets scatter unpredictably, they can hit both military targets and civilian areas.
In densely populated regions, this can lead to devastating consequences.
Why Israel Says These Weapons Are Difficult to Intercept
Israel maintains some of the most advanced missile defense systems in the world, including systems designed to intercept incoming rockets and ballistic missiles.
However, cluster munitions present a unique challenge.
When a missile carrying cluster submunitions is intercepted before the warhead opens, the threat can be neutralized. But if the missile releases its bomblets before interception, the situation becomes much more complicated.
Once dispersed, the dozens of small explosives spread across a wide area and become extremely difficult to destroy individually.
Israeli officials say this characteristic makes cluster munitions particularly problematic for their defense systems.
The Arrow missile defense system is designed to intercept ballistic missiles at high altitudes, but if the warhead opens before the interception occurs, the bomblets may continue falling toward the ground.
Similarly, the Iron Dome defense system is primarily built to stop short-range rockets and artillery shells rather than multiple small explosives dispersed from a single missile.
As a result, once cluster bomblets spread across the sky, there is often little that air defense systems can do to stop them.
How the Bomblets Threaten Civilians
Cluster bomblets are typically small explosives weighing only a few kilograms. Despite their small size, they can cause severe injuries or fatalities when they explode near people, vehicles, or buildings.
Experts say these weapons are particularly dangerous in urban environments because they spread across large areas without distinguishing between military and civilian targets.
One of the most serious risks comes from unexploded submunitions.
Many bomblets fail to detonate upon impact due to technical issues, terrain conditions, or damage during deployment. These unexploded bombs can remain hidden on the ground, acting like land mines.
They may explode days, weeks, or even years later when someone accidentally touches or moves them.
Human rights organizations warn that children are often among the victims because the small objects can resemble toys or harmless debris.
Israeli Authorities Warn the Public
Israeli officials have recently taken unusual steps to educate citizens about the risks posed by unexploded cluster bomblets.
Normally, Israel restricts the release of information about missile strikes and damage. However, the government has begun sharing details about cluster munitions to ensure civilians understand the danger.
The Israeli military’s Home Front Command has distributed public warnings and safety instructions, urging people to report suspicious objects instead of approaching them.
Authorities have also released public service announcements reminding residents that unexploded bomblets can remain dangerous long after the attack.
Emergency services are working with bomb disposal teams to locate and neutralize unexploded submunitions found in residential areas.
Evidence of Cluster Munitions in Israel
Independent researchers and defense analysts have reported evidence suggesting that cluster munitions have been used during the conflict.
- Images circulating online appear to show unexploded submunitions scattered in several locations within Israel.
- Organizations such as the Open Source Munitions Portal have verified some of these images using open-source intelligence techniques.
- The analysis suggests that some Iranian missiles may contain cluster warheads designed to disperse multiple explosives across wide areas.
While the Israeli military has confirmed the presence of unexploded submunitions, officials have avoided publicly discussing the specific types of missiles involved.
Types of Missiles Believed to Carry Cluster Warheads
Iran possesses several missile systems capable of carrying cluster munitions.
- According to defense analysts, the Khorramshahr missile is one of Iran’s largest medium-range ballistic missiles and is believed to have the ability to carry multiple warheads or submunitions.
- Another system reportedly capable of deploying cluster payloads is the Zolfaghar missile, a shorter-range ballistic missile used by Iran’s armed forces.
- Israeli officials claim that the cluster warheads fired during the conflict may contain between twenty and twenty-four bomblets, each carrying several kilograms of explosives.
When released at high altitude, these bomblets spread across large areas, making them difficult to predict and intercept.
Why Cluster Munitions Are So Controversial
Cluster munitions have been the subject of international controversy for decades.
- Critics argue that their wide-area effects make them inherently indiscriminate, especially when used in or near populated areas.
- Because many bomblets fail to explode immediately, the weapons can continue to endanger civilians long after a conflict has ended.
This lingering threat has led to global campaigns aimed at banning the weapons.
In response to these concerns, more than 120 countries signed the Convention on Cluster Munitions, an international treaty that prohibits the use, production, and stockpiling of cluster bombs.
However, several major military powers—including Iran, Israel, and the United States—have not joined the treaty.
Historical Use of Cluster Munitions
Cluster bombs have been used in conflicts around the world for more than eighty years.
They were first widely deployed during World War II, when Nazi Germany used “butterfly bombs” against the United Kingdom.
Since then, many countries have used cluster munitions in various wars.
The United States deployed them in conflicts such as Vietnam War, Iraq War, and War in Afghanistan.
Cluster munitions were also widely used during the 2006 Lebanon War, when Israel fought Hezbollah militants in southern Lebanon.
United Nations demining teams later reported that large numbers of unexploded bomblets remained scattered across the region after the war ended.
More recently, cluster munitions have been reported in conflicts such as the Russian invasion of Ukraine, highlighting their continued use despite international criticism.
Legal and Ethical Debate
Although cluster munitions are restricted under international humanitarian law when used in civilian areas, they are not universally illegal.
- Countries that have signed the Convention on Cluster Munitions have committed to banning the weapons entirely.
- However, nations that have not joined the treaty can still legally possess and deploy them under certain circumstances.
- Human rights groups argue that their humanitarian consequences make them unacceptable under any conditions.
The debate continues to divide military strategists and international law experts.
Supporters of the ban say the weapons create unnecessary civilian suffering, while some governments argue they remain militarily useful against certain targets.

FAQs
What are cluster munitions?
Cluster munitions are weapons that release multiple smaller explosives over a wide area. A larger missile or bomb disperses dozens of smaller bomblets that explode upon impact or remain on the ground as unexploded hazards.
Why are cluster bombs considered dangerous?
They are dangerous because they spread explosives over large areas without precise targeting. Many bomblets fail to detonate immediately, becoming hidden explosives that can injure civilians long after a conflict ends.
Are cluster munitions illegal?
Cluster munitions are banned under the Convention on Cluster Munitions, signed by more than 120 countries. However, some nations—including Iran, Israel, and the United States—have not joined the treaty.
Why are they difficult for missile defense systems to stop?
Once the main missile releases dozens of smaller bomblets, air defense systems cannot easily intercept each one individually. This makes cluster munitions harder to defend against compared to single warhead missiles.
What should civilians do if they find unexploded bomblets?
Authorities advise civilians never to touch suspicious objects. Instead, they should immediately report them to emergency services or military authorities trained to safely dispose of unexploded explosives.
Conclusion
The allegations that Iran has used cluster munitions during its conflict with Israel have renewed global attention on one of the most controversial weapons in modern warfare. While militaries argue that these weapons can be effective against dispersed targets, their widespread impact and long-lasting danger to civilians have made them a subject of intense international criticism.Cluster bomblets that fail to explode immediately can remain lethal for years, turning former battlefields into hazardous zones long after the fighting ends. This risk has led many countries to ban the weapons through international treaties, though some major military powers continue to possess and potentially deploy them.
