The death toll in Lebanon has more than doubled since Friday, when Israel carried out a strike against Hezbollah that killed a senior member wanted by the U.S. for a series of bombings more than 40 years ago.

Tensions between Israel and Hezbollah have intensified in recent days amid an escalation in cross-border warfare since the start of Israel’s deadly war on the Gaza Strip, which has killed nearly 41,400 people, mostly women and children, following a cross-border attack by the Palestinian group Hamas on Oct. 7 last year.

Israel launched a wave of airstrikes against Hezbollah targets in southern Lebanon, just as the militant group’s leader said two days of exploding pagers and walkie-talkies amounted to a declaration of war.
