Israeli troops occupying the foothills of the Golan Heights have shelled the edge of a south Lebanese village for the second time in 48 hours.
Witnesses, including a Reuters correspondent, said Israeli soldiers in the disputed Shebaa Farms area fired around five mortar shells which landed on olive groves in Seddanah, a hilly area on the outskirts of Kfar Shouba village in Lebanon. There were no reports of casualties.
Israel has denied the shells had landed in Lebanese territory.
"There are military exercises being conducted in the area, but they are not even directed at the Lebanese border," an Israeli military source said.
"As a result there are boom sounds which can be heard across the border. But the exercise is carried out entirely in Israeli territory," the official added. Israel has also denied firing on Friday at Kfar Shouba, which faces Shebaa Farms.
Israeli troops in Shebaa Farms occasionally fire shells, including tank rounds, into Lebanese territory to head off suspected infiltration by Hizbollah guerrillas.
The shelling has increased in the past weeks, as have Israeli military flights over Lebanese territory.
The Israeli military operations come at a time when Israel has accused Iran of arming Hizbollah guerrillas with Katyusha rockets capable of striking Israeli cities.
