Lebanese state media has reported several incidents of Israeli blasts targeting houses in border villages in recent days.
Israel’s Channel 12 broadcast footage on Friday that appeared to show one of its presenters detonating a building while embedded with Israeli troops in the south Lebanon village of Aita al-Shaab.
Hezbollah says it is fighting Israeli troops at close quarters in Lebanese border villages.
The two sides began exchanging cross-border fire last year, but all-out war erupted on Sep 23, when Israel ramped up its air campaign against Hezbollah strongholds in south Lebanon, the capital Beirut and the eastern Bekaa Valley.
The war has left at least 1,615 people dead in Lebanon, according to an AFP tally of health ministry figures though the real number is likely to be higher due to gaps in the data.
The war has displaced at least 1.3 million people, according to the International Organization for Migration. More than 800,000 have sought refuge inside Lebanon while more than half a million have fled to Syria, most of them Syrians, according to Lebanese authorities.
