Israeli strikes killed at least nine people in southern Lebanon, Lebanese authorities said Monday, the deadliest day since a ceasefire brokered by the United States and France came into effect last week.

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

The Israeli military said on Monday it struck dozens of targets throughout Lebanon, shortly after Hezbollah accused Israel of violating a ceasefire agreement and fired missiles on an Israeli military position in the disputed Shebaa Farms area.
