In the aftermath of the October 7 massacre, during which more than 250 Israelis were abducted, Israel’s security agencies launched a series of operations aimed at obtaining actionable intelligence on the hostages and working toward their rescue, Mako reports.

One former captive who has since been freed recounted to Mako an unusual incident that took place while he was being held underground in Gaza. He said that on one occasion, as he sat inside a tunnel, his captor stepped away to relieve himself. At that moment, a camera suddenly lowered from the ceiling of the tunnel and began recording him.

According to the hostage, once the terrorist returned, the device retracted back into the ceiling, leaving the captor unaware that any surveillance had taken place. Throughout his time in captivity, the hostage did not mention the episode to his captors. Only after he was back in Israel did he learn that the camera had been part of an IDF operation.

Mako reported that this was not an isolated occurrence. Over the course of the war, there were multiple instances in which Israel’s security establishment managed to document hostages being held inside tunnel networks.

Earlier in the week, Mako also revealed that the IDF employed a specialized and classified capability—details of which cannot be disclosed—that enabled Israeli forces to compel terrorists to emerge from a tunnel in Gaza as part of efforts to secure the return of hostages.

Senior security officials observed the mission in real time from Israel, closely tracking its progress. When it became clear that the operation had not succeeded, those involved experienced significant disappointment.

The original strategy had envisioned extracting the hostages and relocating them to a confidential site within Israel for several days, with the goal of potentially repeating a similar maneuver afterward. Following the failed attempt, however, the approach was scrapped and has not been deployed again.
