IDF uncovers largest-ever Hamas attack tunnel, near northern Gaza border crossing | 17 Dec 2023 | The Israel Defense Forces on Sunday revealed the largest-ever Hamas attack tunnel discovered by the military, in the northern Gaza Strip, close to the Erez border crossing with Israel. The tunnel, of which around four kilometers (2.5 miles) were uncovered by the IDF, goes down some 50 meters (165 feet) underground in some areas and appears to be wide enough for vehicles to pass through. It did not enter Israeli territory. One of the shafts was found just 400 meters (a quarter mile) from the Erez Crossing, which until Hamas’s October 7 onslaught facilitated the movement of Palestinian civilians into Israel for work and medical care.
