The United Nations peacekeeping mission in Lebanon said Sunday that one of its members was wounded by an Israeli grenade dropped near a UN position in the country’s south, the third incident of its kind in just over a month.

The United Nations Interim Force in Lebanon (UNIFIL) has been working with the Lebanese army to support a November ceasefire that sought to end more than a year of hostilities between Israel and militant group Hezbollah that culminated in two months of open war.

“Just before noon yesterday, an Israeli drone dropped a grenade that exploded near a UNIFIL position” in Kfar Kela, the force said in a statement published on Sunday.

“One peacekeeper was lightly injured and received medical assistance.”

Earlier this month, UNIFIL said Israeli drones had dropped multiple grenades near peacekeepers providing security for workers clearing rubble left over from the war.

And in a similar episode in September, UNIFIL said Israeli drones had dropped four grenades near peacekeepers, with Israel insisting at the time that there had been “no intentional fire” directed at the force.

UNIFIL said Saturday’s incident represented “another serious violation of resolution 1701 and concerning disregard for the safety of peacekeepers”.

UN Security Council Resolution 1701 ended a 2006 conflict between Israel and Hezbollah and formed the basis of the November ceasefire.

Under the US-brokered ceasefire, Hezbollah and Israel were both required to withdraw from south Lebanon, while UNIFIL deployed there alongside the Lebanese military, in part to help dismantle Hezbollah infrastructure.

Israel has kept up regular strikes in Lebanon on what it says are Hezbollah targets despite the truce, and has maintained its troops in five locations it deems strategic.

“We again call on the (Israeli army) to cease attacks on or near peacekeepers, who are working to rebuild the stability that both Israel and Lebanon have committed to restore,” the UN peacekeeping force said.

UNIFIL has been deployed since 1978 to separate Israel and Lebanon, and numbers some 10,000 personnel from almost 50 countries.

In August, the Security Council voted to end UNIFIL’s mission in 2027.
