The United Nations Interim Force in Lebanon (UNIFIL) said Friday that a drone dropped a hand grenade near one of its patrols during a planned mission near the southern Lebanese town of Adeisse.

The UNIFIL reported on the US social media company X that peacekeepers with the UNIFIL were conducting a scheduled patrol near Adeisse when local residents warned them of a potential danger inside a house.

The patrol found “an explosive device connected to a detonating cord” and established a security cordon, UNIFIL added.

As the peacekeepers prepared to inspect another nearby house, “a drone hovering overhead dropped a hand grenade at a distance of about 30 meters from the peacekeepers,” the statement said. It was unclear if the grenade exploded or not.

UNIFIL said it sent an immediate stop-fire request to the Israel Defense Forces, holding the Israeli military responsible for “endangering the lives of civilians and peacekeepers” through its activities on Lebanese territory.

“These actions constitute violations of UN Security Council Resolution 1701,” UNIFIL said, warning that any conduct placing peacekeepers at risk “undermines stability in southern Lebanon.”

UNIFIL was established in 1978 following Israel’s invasion of southern Lebanon and saw its mandate significantly expanded after the 2006 war between Israel and Hezbollah under Resolution 1701.

More than 10,000 peacekeepers were deployed to monitor the cessation of hostilities and support the Lebanese army’s presence south of the Litani River.

Resolution 1701, adopted in August 2006, calls for a halt to hostilities between Israel and Hezbollah and the creation of a weapons-free zone between the UN-demarcated Blue Line and the Litani River, except for Lebanese army forces and UNIFIL.

The UN Security Council decided in August 2025 to end UNIFIL’s mandate on Dec. 31, 2026, followed by a one-year plan for a phased drawdown of forces.

Israel has continued violating the ceasefire with Hezbollah in place since late November 2024, resulting in hundreds of casualties, while Israeli forces remain on five Lebanese hills seized in the latest war, in addition to other areas occupied for decades.
