The head of Hezbollah on Sunday threatened Israel after a "drone attack" on the Lebanese Shiite movement's Beirut stronghold, vowing to "do everything" to thwart future attacks.
Hezbollah, considered a terrorist organisation by Israel and the
United States, is a major political actor in
Lebanon and a key government backer in war-torn Syria.
The Shiite movement and Israel, which have fought several wars, have upped their belligerent rhetoric in recent months.
