Meanwhile, the Foreign Ministry instructed 10 Israeli diplomatic missions to protest what it characterized as UNIFIL's "inadequate handling" of Hezbollah's rearmament campaign in southern Lebanon.
On Wednesday, the UN peacekeeping force in Lebanon said ammunition which had exploded in a southern village was a "serious violation" of the UN-brokered ceasefire that ended the Second Lebanon War in 2006.
Lebanese security officials said a series of explosions Tuesday in an abandoned building near Lebanon's tense border with Israel was caused by a fire in a Hezbollah weapons depot. Hezbollah has not comments.
Israel says the incident shows that Hezbollah continues to hide rockets aimed at targeting Israel in Lebanese villages, thereby risking the lives of local residents who are used as a human shield by the terror group.
