Hezbollah’s deadly attack against an army base deep inside Israeli territory presents a major headache for Israel as it continues to struggle to defuse the threat posed by the group.

Sirens wailed Saturday morning in Israel, warning of incoming fire from Lebanon, with a drone launched toward Israeli Prime Minister Benjamin Netanyahu’s house in Caesarea, the Israeli government said.

It is unclear whether Sinwar’s death will lead to a ceasefire between Hamas and Israel, which pounded Gaza with strikes on Saturday. Over 42,000 Palestinians have been killed since the Oct. 7 massacre, according to the Palestinian Health Ministry, which does not distinguish between combatants and civilians.
