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.

At least two people were wounded by Israeli fire in southern Lebanon on Thursday, according to state media. The Israeli military said it had fired at people trying to return to certain areas on the second day of a ceasefire with the Hezbollah militant group.

In a newspaper column, the mayor of Kiryat Shmona, close to the border, said he doubted the ceasefire would be enforced, demanding that Israel creates a buffer zone in south Lebanon. In a poll commissioned by the Israeli station Channel 12 News those questioned were roughly split between supporters and opponents of the ceasefire.
