Health authorities in Gaza have reported that at least 135 disfigured Palestinian bodies, recently returned by Israel, have been traced back to the Sde Teiman detention center. This facility has a longstanding reputation for allegations of torture and unlawful killings, contributing to a growing human rights crisis. These developments have intensified calls for a comprehensive international investigation into Israel’s detention procedures.

The Guardian disclosed that documentation found within each body bag confirms the origin of the remains as Sde Teiman, a military installation and prison camp located in Israel’s Negev desert. The documents, written in Hebrew, included references to DNA tests performed at the facility. “The tags clearly indicate that the remains were held at Sde Teiman,” stated Dr. Munir al-Bursh, the director general of Gaza’s health ministry.

Previously, this site has faced intense scrutiny due to reports by both Israeli and international media outlets. Allegations of Palestinian detainees being blindfolded in cages, shackled to hospital beds, and forced to wear diapers during interrogations have surfaced. Photographs and testimonies from whistleblowers, previously published by The Guardian, depicted prisoners subjected to beatings, sleep deprivation, and other degrading treatments at the facility.

Earlier investigations prompted the Israeli military to launch a criminal inquiry into the deaths of 36 prisoners in military custody at Sde Teiman. This investigation is still in progress. However, new findings from Gaza-based doctors, bolstered by forensic analyses of the returned bodies, have intensified suspicions of systemic torture and extrajudicial executions.

According to medical professionals in Khan Younis, the official examinations and on-site observations strongly suggest acts of murder, summary executions, and systematic torture by Israel. Staff at Nasser Hospital have reported evidence of “direct gunfire at point-blank range” and “bodies crushed beneath Israeli tank tracks.”

The bodies, received in recent weeks as part of a U.S.-brokered truce agreement, arrived in Gaza in sealed body bags marked only with numeric codes, not names. As identification proceeds through DNA testing and photographs, the number of dead linked to Sde Teiman continues to rise. Health staff say some are so mutilated they are unrecognizable.

One of the victims, identified by his brother Rami, was Mahmoud Ismail Shabat, a 34-year-old from northern Gaza. “What hurt us the most was that his hands were tied, and his body was covered with clear signs of torture,” his brother said. Shabat’s mother added, “All our hostages returned tortured and broken. Where is the world?”

The findings align with multiple testimonies from former detainees and whistleblowers who worked at or visited the Sde Teiman facility. A former Israeli medic told The Guardian that “I did witness a patient from Gaza being brought with a gunshot wound to the left chest. He was also blindfolded, handcuffed, and naked as he arrived at the emergency department.” In another case, a detainee’s hand was amputated “because the wrists had become gangrenous due to handcuffing wounds.”

The testimonies describe a harrowing pattern: Palestinian detainees captured during military raids were transported directly to Sde Teiman, where abuse reportedly continued under administrative detention. Some detainees were seized while receiving treatment in Gaza hospitals and subsequently subjected to degrading treatment. “These were patients who had been captured by the Israeli army while being treated in Gaza hospitals,” said a whistleblower. “They had limbs and infected wounds. They were moaning in pain.”

Journalist Shadi Abu Seido, who was detained at Sde Teiman for 100 days, said conditions were so brutal that “many died in detention, others lost their minds.” Seido, who was stripped naked and kept handcuffed and blindfolded for weeks, recalled that guards would bring dogs into his cell and force them to urinate on prisoners. “When I asked why I had been arrested,” he said, “they answered: ‘We have killed all the journalists. They died once. But we brought you here and you will die hundreds of times.’”

Human rights organizations say the details emerging from these accounts indicate crimes that go far beyond abuse. Physicians for Human Rights Israel (PHR) says the confirmed signs of torture “corroborate what we have exposed over the past two years” and demonstrate a pattern of “systematic torture and killings by soldiers and prison guards.”

“The signs of torture and abuse found on the bodies recently returned by Israel to Gaza are horrifying—yet, sadly, not surprising,” said Naji Abbas, director of the prisoners and detainees division at PHR Israel. The group is now calling for an independent international investigation to establish accountability for what it described as “extraordinarily grave violations of humanitarian law.”

Photos provided to The Guardian were reviewed by an Israeli doctor who previously worked at Sde Teiman. Speaking anonymously, the physician confirmed that one victim’s wrists showed signs consistent with “ischemic changes due to excessive restraints.” The doctor added, “This might be someone who was either injured and captured—thus died under Israeli custody—or someone who died due to injuries inflicted after his capture.”

In response to questions from The Guardian, the Israel Defense Forces (IDF) said it had referred the allegations of detainee abuse to the Israel Prison Service but declined to comment on claims that the bodies were held at Sde Teiman. The IDF has maintained that its facilities treat prisoners “appropriately and carefully” and that any claims of abuse are “examined and dealt with accordingly.”

However, human rights experts say such internal investigations lack credibility, pointing to Israel’s record of limited accountability for violations against detainees. The United Nations reports at least 75 Palestinians have died in Israeli custody since October 2023, underscoring what rights advocates describe as a worsening pattern of extrajudicial killings and medical neglect.

UN rapporteur Dr. Morris Tidball-Binz, a forensic science specialist, has called for “independent and impartial forensic assistance” to help identify victims and determine the causes of death. “The preservation and examination of the deceased are vital to ensure evidence is collected responsibly and justice is delivered transparently,” he said.

The scope of what occurred at Sde Teiman remains unclear. Israeli media reports and prisoner-guard testimony suggest up to 1,500 bodies of Palestinians are still stored at the facility. Human rights monitors warn that without access to the site, determining how many detainees died there—and under what circumstances—may be impossible.

For families in Gaza, the slow delivery of the dead compounds their grief with outrage. As one grieving mother said during an interview at Nasser Hospital, “They tortured our sons while the world was silent. Even in death, they came back bound and beaten.”

The mounting evidence of torture and killings at Sde Teiman has intensified calls for transparency and justice. Human rights organizations, journalists, and former detainees insist that only an international investigation—free from Israeli oversight—can uncover the truth. “The evidence is overwhelming,” said PHR. “What is missing now is accountability.”
