The Israeli military said Sunday that its intelligence assessment indicates Hezbollah operatives had opened fire on United Nations peacekeepers in southern Lebanon during the ongoing ceasefire, killing one soldier and wounding three others, two of them seriously.

According to the Israeli army, which said it conducted an operational and intelligence investigation into the incident, the attack occurred while a UN Interim Force in Lebanon (UNIFIL) team was operating in the Ghandouriyeh area to clear unexploded ordnance. The military said a Hezbollah cell opened fire on the unit during the operation.

The Israeli military accused Hezbollah of exploiting the ceasefire to continue what it called “terrorist activity,” saying the group is “endangering and harming civilians and international organizations in Lebanon.”

The statement appears to support remarks by French President Emmanuel Macron, who said Hezbollah was responsible for the killing of a French soldier in what Paris described as an “ambush.”

The slain peacekeeper was identified by France’s armed forces ministry as Staff Sergeant Florian Montorio, who was killed by a direct gunshot.

UNIFIL strongly condemned the incident, attributing responsibility to what it described as “non-state actors”—a term commonly used to refer to Hezbollah. The UN mission also said it had launched its own investigation into the circumstances surrounding the attack.

Hezbollah denied any involvement, urging caution in drawing conclusions and expressing surprise at what it described as premature accusations.
