"We have dismantled, most of it has been through explosives, more than 150 tunnels and complexes [of Hamas]," Conricus told a briefing late on Saturday.
Such underground structure is a "backbone" of Hamas’ combat capabilities, as the movement uses it to hide and come out unexpectedly, he added.
On October 7, Palestinian group Hamas launched a surprise attack against Israel from Gaza, killing and abducting people in neighboring Israeli communities. Israel retaliated with missile strikes and a complete blockade of the Gaza Strip, home to more than 2 million. On October 27, Israel launched a large-scale ground incursion into Gaza with the declared goal of eliminating Hamas and rescuing the hostages.
