Hezbollah’s leader said on Tuesday his Iran-backed movement had shot down an Israeli drone in Lebanon for the first time to strengthen deterrence against attack by arch-foe Israel. On Monday, Hezbollah said it downed and took possession of an Israeli drone in south Lebanon after a flare-up at the border with Israel around a week ago. The brief exchange of cross-border fire between Hezbollah and Israel marked the fiercest shelling exchange since the long-time enemies fought a deadly month-long war in 2006.
