Israeli forces carried out several new drone and artillery strikes in Lebanon on Tuesday, further shaking a tenuous ceasefire meant to end more than a year of fighting with Hezbollah.

Israel hits Lebanon with its largest wave of airstrikes since agreeing to a ceasefire with Hezbollah, as both sides accuse each other of violations.

As tit-for-tat strikes strain a ceasefire between Israel and Hezbollah less than a week since it went into effect, Israel’s defense minister on Tuesday threatened to directly target the Lebanese state should the agreement fall apart.
