Less than two full days into a ceasefire, Israel's military and Hezbollah were both claiming isolated breaches of the deal.

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.

A cease-fire between Israel and Hezbollah brokered by the U.S. and France took effect in Lebanon early Wednesday, raising hopes of ending more than a year of cross-border strikes and a full-scale war that has killed thousands.
