Israel says it found third 'Hizballah attack tunnel'

Israel said on Tuesday it had uncovered another Hizballah "attack tunnel" infiltrating its territory from Lebanon - the third since it started a search and destroy operation along the border last week.

The military did not reveal the exact location of the tunnel but said it "does not pose an imminent threat".

"Explosive devices have been placed inside the tunnel by the IDF (Israel Defence Forces)," it said in a statement.

The army announced an operation on December 4 dubbed "Northern Shield" to destroy tunnels it said were dug under the border by the Shia militant group Hizballah.

"The Lebanese government is held accountable for the attack tunnels dug from Lebanese territory," the military statement said.

"IDF troops will continue to operate in accordance with the approved plan to locate and expose the Hizballah terror organisation's attack tunnels."
