Sources: 5. Developments: 2. Investigations into the death of Palestinian detainee Thair Abu Asab at Ketziot Prison have uncovered evidence of severe physical abuse and misconduct by prison staff. Abu Asab, who had been detained since 2005, died following an assault in which suppression units used batons and dogs against inmates. Autopsy results indicated that the assault caused heart wall tears and multiple rib fractures, leading to cardiac and respiratory failure. Evidence from investigation files includes video footage of the incident and internal communications among guards. Messages revealed staff discussing the physical abuse of inmates and expressing satisfaction regarding the death, with one guard reportedly messaging a partner, ‘My love, he just died,’ and another stating, ‘We beat them badly.’ In September 2026, the Israeli Prosecution filed an indictment against 12 members of the Israel Prison Service, including a shift leader and members of the ‘Keter’ unit, in connection with the death of Abu Asab and the assault of eight other detainees. ## Timeline ### 2026-09-25: Thair Abu Asab death: Video emerges of fatal prison assault Video footage has surfaced showing the final moments of Palestinian detainee Thair Abu Asab, who died after a prison guard assault at Katziot Prison.
