The heir-apparent to Hezbollah‘s late Hassan Nasrallah has been out of contact since Friday following an Israeli airstrike targeting him. Israel launched the strike on Friday local time against Hashem Safieddine,

It comes after Israel’s attack on the northern Beddawi camp killed an official with Hamas’ military wing and his wife and two young daughters, the Palestinian militant group said. Hamas later said another military wing member was killed in Israeli strikes in Lebanon’s eastern Bekaa Valley.

Israel has said it has targeted Hezbollah 's intelligence headquarters in Beirut as part of strikes against the militant group's leadership – with Iran 's Ayatollah Ali Khamenei vowed that Tehran and its proxies would not back down.
