There’s an active Hamas attack tunnel deep inside Israeli territory, some 20 kilometers (12 miles) from the Gaza Strip, stretching tens of meters and full of hiding spots, offshoots and storage depots. There are others like it, too.
But unlike the three border-crossing attack tunnels that the Israel Defense Forces has destroyed in the past three months, these are nothing to worry about.
Since the 2014 Gaza war, also known as Operation Protective Edge, the Israeli military has constructed multiple replicas of Hamas tunnels in the grounds beneath military bases across the country, including two of the largest ones under the Southern Command Training Base, known in the army by the Hebrew acronym Baf Darom.
