As of Saturday night, the IDF has uncovered 34 terror tunnels, including 5 which extend from Gaza far into Israel, the IDF Spokesperson's Office announced Saturday night.
The tunnels have been neutralized and are in the process of being destroyed, it said.
Seventy terrorists have been killed - including 20 on Saturday alone - and an addition 13 were taken into Israeli custody for questioning after surrendering on Friday.
The IDF has attacked more than 450 terrorist targets since the ground offensive was launched.
Several of the IDF's elite combat forces are currently in Gaza, including the Paratroopers, Nahal, Givati, Tanks, Engineering Corps, and Special Forces.
Late Saturday, Hamas's "military wing," the Ezzedine Al-Qassam Brigades, said its terrorists clashed with "Israeli special forces" in a house east of Khan Yunis, in southern Gaza, wounding some of them, according to AFP. The IDF denied that any soldiers were wounded in this incident.
Later on Saturday, the IDF said it killed a militant who had "emerged from a concealed tunnel shaft while firing at" Israeli soldiers, who "immediately retaliated, killing the terrorist."
A military spokeswoman told AFP the incident took place within southern Gaza, adding she was not aware of Israeli casualties.
Operation Protective Edge was launched twelve days ago to protect Israel from a constant barrage of rocket fire from Gaza.
Since the beginning of the operation, 1,497 rockets have been launched at major Israeli population centers. Of those, 1,093 rockets hit Israel; 301 were intercepted by the Iron Dome missile defense system. An additional 100 were estimated to have hit Gaza itself, causing an untold number of Palestinian Arab deaths.
The IDF has attacked over 2,037 terror targets - by ground, by air, and by sea.
