Israel's army estimated on Thursday that a few weeks remain in its operation to locate and destroy Hezbollah attack tunnels crossing into its territory from Lebanon.
An army spokesman made the comments as he announced that tunnels found dug from the Lebanese town of Kafr Kila towards the Israeli town of Metula had been successfully destroyed by pumping sealing material into them.
He declined to say how many were found coming from Kafr Kila, but Israel has so far announced the discovery of five cross-border tunnels from different locations in Lebanon since the operation began on December 4.
The army distributed video and photos appearing to show the sealing material flowing out from a building in Lebanon.
"The footage that we have sent clearly indicates exactly what happened and shows beyond any doubt that the tunnels did indeed cross from Lebanon into Israel," army spokesman Jonathan Conricus told journalists.
He added that "we still have probably a few weeks, but that's an estimate ... The operation will end once all of these cross-border attack tunnels have been found and destroyed".
The IDF stated that it holds the Lebanese government responsible and accused Hezbollah of using civilian structures as cover to hide the tunnels.
On Wednesday, it said it had used explosives to destroy another cross-border tunnel dug from the Lebanese village of Ayta ash Shab.
The highly publicized operation has gone ahead without drawing a military response from Hezbollah.
