Al-Qassam Website _ The Ezzeddin Al-Qassam Brigades, the military wing of the Hamas Movement, has unveiled exclusive footage and documentations detailing the life and legacy of the late Commander-in-Chief of its Staff, Mohammed Al-Deif "Abu Khaled".

Featured in a high-profile episode of Al Jazeera’s program (Tip of the Iceberg) entitled "The Secrets of the Shadow Man," the report released an exclusive recorded audio testimony by Al-Deif himself. The recording chronicled pivotal turning points in the Brigades' history—from the initial founding days of armed operations and his early detention to his decades-long leadership of the Brigades, concluding with his masterminding and management of Operation Al-Aqsa Flood up until the moments prior to his martyrdom.

Exclusive Audio Testimony Chronicles History of the Brigades

The testimony recounted early undercover night movements and tough tactical training sessions across the mountains of the occupied West Bank. At the time, these maneuvers dominated Israeli occupation military intelligence and the Zionist enemy's media, sparking shock over how fighters could freely move between the southern and northern West Bank to execute coordinated operations in Hebron and Ramallah without being detected.

Early Undercover Operations in the West Bank

The broadcast also highlighted the historic Ganei Tal operation—the first direct military response to the colonial occupation's deportation of resistance leaders to Southern Lebanon's Marj al-Zuhour—which sent an unyielding message that the armed resistance would continue unabated.

Inside the Underground War Room — Days Before October 7

The investigative report aired never-before-seen footage recorded from inside the Al-Qassam Brigades’ underground central war room just days prior to the historic operation on October 7, 2023.

The footage showed Al-Deif in clear view and good health, actively directing military strategy alongside his General Military Council, reviewing terrain maps, and finalizing the operational blueprints for Al-Aqsa Flood. This live documentation completely shattered decades of Israeli occupation disinformation campaigns that claimed Al-Deif had been left completely paralyzed or incapacitated after surviving more than seven complex assassination attempts orchestrated by the terrorist enemy intelligence services.

This visual record bridged the historic timeline leading up to the official announcement by Qassam military spokesperson late Abu Obaida in early 2025, which formally announced the martyrdom of Commander-in-Chief Mohammed Al-Deif alongside prominent members of the Military Council and Operations Staff—most notably his deputy Marwan Issa, Khan Younis Brigade Commander Rafe' Salama, Head of the Weapons Staff Ghazi Abu Tama'a, and Head of Human Resources Raed Thabit—following the massive air raids that targeted the Al-Mawasi area in Khan Younis on July 13, 2024.

Confirmation of Martyrdom and Legacy

The "Tip of the Iceberg" investigation stands as an unprecedented historical and military record, bringing Al-Deif out of the legendary story of the "Shadow Man" to offer direct, verified testimony—in his own voice and image—on how the resistance built a military apparatus capable of shifting the strategic balance of the struggle.

Ultimately, the documentation provided definitive proof that prior to his martyrdom, Mohammed Al-Deif succeeded in transforming the Palestinian resistance from hunted cell networks and locally funded guerrilla units into a disciplined military force equipped with resilient institutions—one fully capable of waging major strategic battles even after the martyrdom of its Commander-in-Chief.
