Human Rights Watch (HRW) has recently spotlighted serious concerns regarding Hezbollah’s alleged illicit use of cluster munitions during attacks on Metula, northern Israel, on March 4 and 15, 2026. The organization is urging for an independent investigation into these incidents to ensure accountability and transparency.
Investigation Findings
HRW researchers visited Metula in May and conducted interviews with four witnesses. They also examined impact sites, photographs, and video evidence. Although no civilian casualties were reported in either attack, Hezbollah admitted to launching rocket strikes on both dates but denied using or possessing any cluster munitions. The incident on March 4 involved a residential street, and investigators found seven craters that appeared to be consistent with submunition impacts; one local resident mentioned that the military counted approximately 50 such impacts. On March 15, footage captured about 30 distinct explosions near the entrance of the town, with a resident recalling instructions for locals to stay indoors for a full day while soldiers ensured the area was secured from explosives.
The Implications of Cluster Munition Use
Patrick Thompson, a researcher with HRW, emphasized that utilizing cluster munitions in civilian zones constitutes a blatant violation of international law. He asserted that such actions could be classified as a war crime due to the way these munitions open in the air and disperse smaller explosives over a wide area. This creates lasting dangers since unexploded ordnance can threaten civilians long after conflicts have ended. The International Committee of the Red Cross (ICRC) has issued warnings about the peril posed by these remnants, especially for those attempting to rebuild their homes, cultivate their land, or remove debris following hostilities.
Legal Framework and Obligations
The 2008 Convention on Cluster Munitions outright prohibits states from using, producing, acquiring, stockpiling, or transferring such weapons. Lebanon ratified this convention on November 5, 2010, but Israel remains a non-party. The convention also mandates that states party to it must clear contaminated areas, assist victims, and destroy stockpiles of these munitions.
Under Article 9 of the convention, states are required to establish measures, including criminal penalties, to deter any prohibited actions within their jurisdictions. Notably, the prohibition against indiscriminate attacks is applicable independently of the treaty that bans cluster munitions. This aspect aligns with international humanitarian law, which demands that parties to a conflict must distinguish between military objectives and civilians, while also taking necessary precautions to mitigate civilian harm.
Wider Context and Humanitarian Concerns
During an April 24 briefing, the UN human rights office presented evidence suggesting that Hezbollah had targeted Israeli residential areas with unguided rockets. Its investigations also documented devastating Israeli strikes that led to the destruction of residential buildings in Lebanon, claiming the lives of entire families and affecting medical personnel. Additionally, the recently released Cluster Munition Monitor 2026 reported that at least 1,063 people were killed or injured globally by cluster munitions in 2025, with 87 percent of casualties identified as civilians.
The serious allegations against Hezbollah and the calls for thorough investigations reflect broader concerns about compliance with international law in conflict scenarios. As the humanitarian ramifications of these conflicts continue to unfold, the push for accountability and adherence to legal standards remains critical in safeguarding civilian lives.
