America has laid the blame for the flare-up on Israel’s northern border with the Lebanese.
The US State department called the attack, which left an Israeli commander and three others dead, "totally unjustified and unwarranted".
Lebanon had initially accused Israeli forces of provoking the fighting by crossing the border as they carried out maintenance work on a tree.
But United Nations peacekeepers probing the incident said Israel had been doing “routine work south of the international borderline”.
