Israel's military said Tuesday it has begun an operation to "expose and thwart" cross-border attack tunnels from Lebanon that were dug by the Iran-backed Lebanese movement Hezbollah.

Lt.-Col. Jonathan Conricus, an Israeli military spokesperson, said it had detected tunnels crossing from Lebanon into northern Israel. He said the Israeli operation to counter the tunnels would be inside Israel, and would not cross the border.

Israel released video footage of digging and pile-driving equipment at work in unidentified locations, carrying out what it said were "tactical preparations to expose Hezbollah's offensive cross-border tunnel project." Reuters could not immediately verify the footage.

The situation appeared calm on the Lebanese side of the border where UN peacekeepers and Lebanese troops were deployed as usual, a Reuters journalist there said. There was no immediate comment from Hezbollah.

Israel and Hezbollah have avoided any major conflict across the Lebanese-Israeli border since their last war in 2006, though Israel has mounted attacks in Syria targeting what it said were advanced weapon deliveries to the Shia group.

On Monday, Israeli Prime Minister Benjamin Netanyahu met U.S. Secretary of State Mike Pompeo in Brussels. An Israeli government source said the meeting was to update Pompeo of the upcoming tunnel operation.

The current focus of operations was near the Israeli border town Metulla, Conricus said. He said some areas near the border fence had been closed off. An Israeli military source said the operation might take weeks to complete.

The United Nations Interim Force in Lebanon said the situation in its area of operation "remains calm" and it is co-ordinating with relevant parties to maintain this stability.

'Violation of Israeli sovereignty'

The military said the tunnels were not yet operational, but posed "an imminent threat" to Israeli civilians and constituted "a flagrant and severe violation of Israeli sovereignty."

It said the army had "enhanced its presence and readiness" and was prepared for "various scenarios."

In September, INetanyahu identified three locations in Lebanon where, he said, Hezbollah was converting "inaccurate projectiles" into precision-guided missiles.

During a televised address last month, Netanyahu hinted at an upcoming Israeli offensive, saying: "I will not say this evening when we will act and how. I have a clear plan. I know what to do and when to do it. And we will do it."

He said an upcoming security challenge would require Israelis to "endure sacrifice."

Last year, Hezbollah's leader said any future conflict with Israel could take place inside Israeli territory, and there would be "no place that is out of reach of the rockets of the resistance or the boots of the resistance fighters."

Israel's vulnerability to tunnels was laid bare during its war with Palestinian militant group Hamas in Gaza in 2014 when Palestinian militants used dozens of secret passages dug from Gaza into Israel to launch surprise attacks.
