The Israeli military said that the drone crash in an open area on Friday night posed "no risk of leaked information." It provided no further details.

Hezbollah television station Al-Manar reported that the "spy drone" fell between Baraachit and Beit Yahoun in southern Lebanon.

It said that "a second spy plane targeted it with a guided missile, which resulted in it being destroyed."

Israel and Shiite militant group Hezbollah, based in neighbouring Lebanon, fought a devastating war in 2006 and the two remain bitter enemies.
