Israeli jets Sunday launched an airstrike over a southern Lebanese border village, while troops shelled other border towns and villages still under Israeli control, Lebanon’s state-run National News Agency reported.

At least two people were killed on Monday in Israeli strikes on southern Lebanon, Lebanese authorities said, as a ceasefire ending more than a year of hostilities between Israel and Lebanese armed group Hezbollah appeared increasingly fragile.

President Biden said the 60-day truce, which the United States helped broker, would take effect early Wednesday, and was intended to become permanent, ending Lebanon’s deadliest war in decades.
