Israeli shelling struck a Lebanese army observation post at the border on Friday, three sources in Lebanon told Reuters, after the Israeli military warned of a suspected armed infiltration that it said it was responding to with artillery fire.
Israel later ruled out that any incursion had occurred and residents of a village near the border, who had been instructed to hole up at home and lock doors and windows, were told they could again go outdoors.
A well-placed Lebanese security source said Palestinian groups had tried an armed infiltration that included an attempt to breach the border fence near the Lebanese town of Alma Al-Shaab.
The alert was issued in Hanita, 500 metres (yards) from the border and opposite Aalma El-Chaeb.
The military statement said there had been an explosion at the adjacent border fence, which was lightly damaged.
Lebanese state media reported that shells struck near Alma Al-Shaab and Dhayra, the sites of repeated clashes in the past week, the deadliest at the border since Hezbollah and Israel fought a brutal month-long war in 2006.
