Israel said on Thursday that its ceasefire with Hezbollah was breached hours after Lebanese security sources said Israeli tanks attacked six areas of southern Lebanon, calling into question a truce reached after more than a year of fighting.

The ceasefire agreement between Hezbollah and Israel brokered by the United States and France was characterized by President Biden as an attempt to deliver a "permanent cessation of hostilities."

Israel said it conducted an air strike on a Hezbollah weapons facility on Thursday, the first since a ceasefire in the war in Lebanon took effect.The truce, which came into force on Wednesday, seeks to end a war that has killed thousands in Lebanon and sparked mass displacements in both Lebanon and Israel.
