Palestinians said an Israeli strike killed at least 22 people in a school sheltering displaced people in southern Gaza City on Saturday, while the Israeli military said the attack targeted a Hamas command centre.

The strike in Beirut extended a string of Israeli attacks that have injured thousands and left U.S. and regional officials worried about a wider conflict.

The strike on a suburb of Lebanon’s capital killed Ibrahim Aqil, a prominent Hezbollah leader, and other senior commanders, Israel said. The attack left 14 people dead.

Israel killed a top Hezbollah commander and other senior figures in the Lebanese movement in an airstrike on Beirut on Friday, vowing to press on with a new military campaign until it is able to secure the area around the Lebanese border.

Israel launched a rare airstrike that killed a senior Hezbollah military official in a densely populated southern Beirut neighborhood on Friday. It was the deadliest such strike on Lebanon’s capital in decades,
