Concerns have emerged from Human Rights Watch (HRW) over the alleged use of cluster munitions by Hezbollah in northern Israel. The incidents in question reportedly took place on March 4 and March 15, 2026, targeting the town of Metula, with neither attack resulting in civilian casualties. HRW has called for an independent investigation into these events.
HRW researchers conducted a field visit to Metula, interviewing witnesses and analyzing impact sites, photographs, and videos. Evidence suggested the presence of submunition impacts, with military accounts reporting multiple explosions. Hezbollah, while acknowledging rocket attacks on those dates, has denied using or possessing cluster munitions.
The implications of using cluster munitions in civilian-populated areas are severe, potentially contravening international law. Patrick Thompson, an HRW researcher, emphasized that such use could constitute a war crime, highlighting the dangerous legacy of unexploded ordnance, which threatens civilians long after hostilities cease. The International Committee of the Red Cross (ICRC) has similarly warned of the long-term dangers associated with unexploded cluster munitions.
The 2008 Convention on Cluster Munitions prohibits the use, production, and transfer of these weapons, and obligates parties to eliminate stockpiles and assist victims. Lebanon ratified this treaty in 2010, while Israel has not yet joined. Proper adherence to international humanitarian law mandates that military objectives be distinguished from civilian entities, a fundamental tenet violated by indiscriminate attacks.
In tandem with HRW’s findings, the UN human rights office described Hezbollah’s use of unguided rockets against Israeli residential zones. This was mirrored by reported Israeli strikes on Lebanese infrastructure, adding complexity to the regional conflict dynamics. These concerns are compounded by the findings of the Cluster Munition Monitor 2026, documenting significant global casualties related to cluster munitions, with a substantial civilian toll of 87 percent.
The unfolding situation highlights the urgent need for international scrutiny and accountability. As tensions persist, the call for robust investigatory mechanisms into allegations of cluster munition use emphasizes the commitment to upholding international humanitarian law and protecting civilian populations in conflict zones.
