The entrance to the tunnel CNN entered lay in the rubble of what the Israeli military said was a residential building. After uncovering the site, the military blew a hole through a section of the tunnel – exposing it on two sides in order to outflank Hamas fighters who were inside.

A dark, humid and seemingly endless labyrinth awaited us once inside. Without a light on, the tunnel was pitch-black and it was impossible to hear the outside world.

According to the IDF, the tunnel had been outfitted with wiring – electricity and telecommunications – installed by Hamas. But there were no lights on when CNN visited.

At the end of one section, CNN found what the Israeli military described as a Hamas battalion commander’s office: two large rooms, a bathroom and a kitchen linked by a hallway held up with steel beams.

There were tiled floors, painted walls, plus electricity and plumbing. Large frames also hung on the walls, which the Israeli military said once displayed maps. A large map that would fit one of the frames was sprawled on a table.

Goldfuss, standing inside the command center, said he was surprised at the scale of the tunnels he said the IDF had found.
