One person was killed and 24 others were wounded Monday when an unexploded Hezbollah cluster munition detonated near the Lebanon border in northern Israel. The explosion occurred between Kibbutz Manara and Kibbutz Yiftah and was declared a mass-casualty event by the IDF. Several of the wounded were seriously injured.

Students and staff from ORT Ma’alot Yeshiva High School were among those hurt while on an annual field trip in the area. According to a preliminary investigation by Israel’s Fire and Rescue Authority, one student appears to have placed an explosive device in his bag, which later detonated. The circumstances surrounding how the device was found and handled remain under investigation.

Rescue teams, police officers, bomb disposal experts, Magen David Adom paramedics, and military and Hatzalah helicopters responded to the scene. The wounded were taken to hospitals across northern Israel. Rambam Health Care Campus treated four victims, including three teenagers, while Ziv Medical Center treated 13 and Galilee Medical Center treated six, including one person with serious injuries.

Israel Police Commissioner Daniel Levi visited the scene and said the field trip had received approval from the relevant authorities, to the best of his knowledge. He said he was considering scaling back future field trips to the area while officials reassess the risks to students. Ma’alot Mayor Moti Ben-David said an operations center staffed by social workers and psychologists had been established to support the students, and a bus was sent to pick up those who were not injured.

The incident has renewed warnings about the dangers posed by unexploded munitions left behind during fighting. Orly Silvinger, CEO of child safety organization Beterem, urged parents to explain to children that suspicious objects must never be approached, touched or moved. Anyone who encounters a suspicious object should move away, notify an adult and report it to police by calling 100.
