The Palestinian Ministry of Detainees and ex-Detainees Affairs in Gaza warned that the vast majority of Palestinians detained from the Strip during the war by Israeli forces "disappear into the unknown" within the occupation's prisons, camps, and detention centers.

In a press statement, the Ministry confirmed that the detainees are held in secret detention centers, such as the infamous Sde Teman detention center in the occupied Negev, where they are subjected to brutal and severe abuse and systematic torture, especially at the beginning of their detention.

It added that Israeli security agencies conduct investigation sessions using various forms of torture in order to "extract confessions and information by any means necessary."

Meanwhile, the Israeli occupation refuses to engage with any institution or entity,  especially the International Committee of the Red Cross, requesting information or visits to any detainee.

The interrogation of a large number of detainees has been concluded, but the occupation still refuses to release them, the statement continued.

The Ministry emphasized that what the detainees endure in the occupation's prisons constitutes "an intended, deliberate crime and a compound crime against our people and prisoners." It highlighted that the occupation practices "killing, execution, and sadism against the prisoners," imposing extremely harsh conditions that violate all international and humanitarian norms and laws.

It condemned "the heinous crimes committed against the prisoners and detainees in Israeli prisons since October 7" and held the Israeli occupation and the US administration "responsible for the ongoing crimes against Palestinian detainees."

As the situation of detainees continues to worsen, the Ministry called for a "serious international investigation into the crimes committed by the Israeli occupation against defenseless detainees."

The Ministry urged for "international pressure on the occupation to open the prisons and secret detention centers to international organizations, institutions, and lawyers" to conduct visits and assess the conditions of the detainees. It also called on the international community and all international human rights organizations and institutions to "assume their responsibilities towards this serious issue, which the world has never witnessed before."

The statement concluded by calling on all Palestinian people and national factions to stand by the families of the detainees and offer them support.

1,000 Palestinians missing

Earlier this month, Palestinian human rights groups reported a lack of information regarding the whereabouts and status of hundreds of Palestinian workers from Gaza.

After the Israeli genocidal war on Gaza was launched last October, “approximately 6,441 workers were deported to the West Bank, and approximately 1,000 workers remain missing in light of the ongoing crime of forced disappearance against Gaza detainees,” the Commission of Detainees' Affairs, the Palestinian Prisoners’ Society, and the Ramallah-based Prisoner Support and Human Rights Association (Addameer) said in a joint statement.

The institutions stated that "Israel" has declined to reveal the location or provide any information regarding the well-being of these individuals. The only information provided by "Israel" is that there are two military camps for Gaza detainees: one near Beer al-Sabe and another near al-Quds.

New Guantanamo

Israeli media had repeatedly broadcast scenes showing dozens of Palestinian detainees of all ages in Gaza stripped naked and blindfolded before being led to an unknown location, sparking international outrage.

Israeli newspaper Haaretz reported last December that hundreds of Palestinians who were detained in Gaza and taken to the Sde Teman base near Beer al-Sabe’ were killed as a result of the harsh detention conditions.

It said that "the age group of the Palestinian detainees killed while under investigation ranges from minors to elderly individuals" and also described how "detainees are locked in fenced areas blindfolded and handcuffed for most of the day, with lights kept on throughout the night.”

Commenting on Haaretz’s report, the Euro-Mediterranean Human Rights Observatory later announced that the testimonies it collected were consistent with the Israeli outlet’s findings regarding the martyrdom of Palestinian detainees from Gaza due to torture in an Israeli center that the Observatory described as a “new Guantanamo".

Among the crimes committed by the Israeli occupation against civilians are forced displacement, field executions, random and arbitrary arrests, and harassment. 

To this end, the Observatory called for "an impartial and urgent international investigation into the Israeli army's field execution of Palestinian civilians after detaining them from various areas across the Gaza Strip."
