Austrian Ambassador to Israel Martin Weiss quoted Prime Minister Benjamin Netanyahu describing the tunnels found up north as 'big enough for troops,' on Thursday during a briefing to the Diplomatic Corps near Metula.

This discovery follows the launch of Operation Northern Shield, which has the goal of exposing and destroying Hezbollah tunnels along the border fence with Lebanon,
