The 1.5-kilometer-long underground network is located about 100 meters from the Rafah crossing and "splits into several different paths at varying depths," according to IDF spokesman Daniel Hagari.
The demolition has dealt a significant blow to Hamas, Hagari said, as the terrorists were using the tunnel to attack Israeli soldiers operating in Rafah.
Hagari said the Israeli military found "short-range anti-tank missiles, Kalashnikov rifles, explosive devices, and grenades" inside the tunnel, which was also equipped with living quarters and bathrooms.
