On a tense Tuesday morning along the southern Lebanon border, a routine UN peacekeeping mission nearly turned tragic. Four grenades, dropped by Israeli drones, exploded perilously close to UNIFIL (United Nations Interim Force in Lebanon) peacekeepers as they worked to clear roadblocks near the village of Marwahin—less than a kilometer from the border line. The incident, which unfolded on September 2, 2025, has since been described by UNIFIL as “one of the most serious attacks on UNIFIL personnel and assets” since the November 2024 ceasefire that ended the 14-month Israel-Hezbollah war, according to reporting from The Guardian and News Today Net.
Miraculously, no one was hurt. But the proximity of the explosions—one grenade detonating within 20 meters (about 20 yards) and three others within approximately 100 meters of UN personnel and vehicles—sent shockwaves through diplomatic and peacekeeping circles. UNIFIL said the Israeli military had been informed in advance of the peacekeepers’ planned road clearance work, which was intended to restore access to a UN position along the so-called Blue Line, the disputed demarcation between Lebanon and Israel.
“Out of concern for the safety of peacekeepers following the incident, yesterday’s work was suspended,” UNIFIL said in a statement cited by News Today Net. The road clearance scheduled for the following day, September 3, was promptly called off, underscoring the gravity of the situation and the risk faced by those tasked with keeping the peace in this volatile region.
In the immediate aftermath, the Israeli military did not issue a comment. However, later on Wednesday, Israeli officials stated that the drones had not intentionally targeted the peacekeepers. Instead, they claimed the drones had dropped several sonic bombs near a suspect in the border area and that they had made contact with UNIFIL to explain what happened. According to The Guardian, the Israeli military reiterated that they had been fully informed in advance about the peacekeepers’ activities.
UN spokesman Stephane Dujarric, when asked whether UN Secretary-General Antonio Guterres accepted Israel’s explanation, responded, “Whether or not they meant to do it … what I can tell you is that the Israeli Defence Forces were fully informed in advance of the work that we were doing on road clearance in that area.” Dujarric added that UN officials were “relieved that no one was hurt. But this could have been very tragic indeed.”
The international response was swift and pointed. France, which contributes a significant contingent to UNIFIL, condemned the attack, emphasizing that “respect of its members applies to all parties without exception.” Qatar went further, labeling the incident a “grave violation of international humanitarian law” and the UN Security Council resolution that ended the Israel-Hezbollah war. Both nations called for accountability and renewed respect for the safety of peacekeeping personnel.
The timing of the incident added another layer of complexity. Just days earlier, the UN Security Council had voted unanimously to terminate the UN peacekeeping force in southern Lebanon at the end of 2026, bowing to demands from the United States and Israel. This decision marks the end of nearly five decades of UNIFIL’s presence in the region, during which the multinational force has played a pivotal role in monitoring the security situation and attempting to prevent renewed hostilities.
UNIFIL’s mission has not been without controversy. While the force has often been hailed for its stabilizing influence, it has also drawn criticism from both sides of the border, as well as from officials in the administration of former U.S. President Donald Trump. Trump’s foreign policy pivot led to significant cuts in U.S. funding for the operation, reflecting a broader shift in America’s approach to international peacekeeping and multilateral commitments.
The context of the recent attack is inextricably linked to the devastating toll of the Israel-Hezbollah war. According to the World Bank, the conflict claimed the lives of more than 4,000 people in Lebanon, including hundreds of civilians, and caused destruction worth $11 billion. In Israel, 127 people died, including 80 soldiers. The war left deep scars on both societies and underscored the importance—and the difficulty—of sustaining peace along one of the world’s most volatile borders.
UNIFIL has made its position clear: any actions that endanger UN peacekeepers or interfere with their mandated tasks are “unacceptable and a serious violation of international law and the resolution that ended the war.” The peacekeeping force has repeatedly emphasized that it is the Israeli military’s responsibility to ensure the safety and security of peacekeepers performing Security Council-mandated duties. “Any actions that endanger UN peacekeepers and assets or interfere with their tasks are unacceptable and a serious violation of international law and the resolution that ended the war,” the force reiterated, according to News Today Net.
France’s condemnation echoed this sentiment. Its officials underscored that the safety of UNIFIL personnel must be guaranteed by all parties—without exception. Qatar’s denunciation, calling the incident a “grave violation,” highlighted the broader international concern that such attacks risk undermining the fragile peace and could set a dangerous precedent as the peacekeeping mission winds down.
The Israeli military’s explanation, while welcomed by some as an attempt to clarify events, did little to quell the unease. Questions remain about how such a near-miss could occur despite prior notification and established protocols. “This could have been very tragic indeed,” said UN spokesman Stephane Dujarric, encapsulating the anxiety felt by many in the international community.
For now, the suspension of road clearance work stands as a stark reminder of the risks faced by peacekeepers in southern Lebanon. The broader implications of the UN Security Council’s decision to end UNIFIL’s mandate are still unfolding. After nearly fifty years of on-the-ground presence, the peacekeeping force is set to depart by the end of 2026, leaving a security vacuum that many fear could reignite tensions.
As the dust settles on this latest incident, one thing is clear: the work of peacekeepers remains as perilous as it is vital, even as their future in southern Lebanon grows increasingly uncertain. The world watches closely, hoping that the final chapter of UNIFIL’s mission does not end with tragedy, but with a lasting peace that has long eluded this troubled border.
