Hamas spent only three hours of Ofer Calderon’s 484-day captivity keeping him above ground, confining the 54-year-old deep underground in their labyrinth of terror tunnels in Gaza where he witnessed systematic torture, and the mastermind behind the October 7, 2023 massacre.

“I recognized him immediately,” Calderon told Channel 12 in his first comprehensive interview since his February release, describing the face-to-face meeting with late Hamas chief Yahya Sinwar deep in Gaza’s tunnel network.

“He was carrying a fax machine that he used to communicate without being intercepted.”
