Israel said the ceasefire was violated after what it called suspects, some in vehicles, arrived at several areas in the southern zone.

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.
