Patients lying shackled and blindfolded on more than a dozen beds inside a white tent in the desert. Surgeries performed without adequate painkillers. Doctors who remain anonymous.

These are some of the conditions at Israel’s only hospital dedicated to treating Palestinians detained by the military in the Gaza Strip, three people who have worked there told The Associated Press, confirming similar accounts from human rights groups.

While Israel says it detains only suspected terrorists, many patients have turned out to be non-combatants taken during raids, held without trial and eventually returned to war-torn Gaza.

Eight months into the Israel-Hamas war, accusations of inhumane treatment at the Sde Teiman military field hospital are on the rise, and the Israeli government is under growing pressure to shut it down. Rights groups and other critics say what began as a temporary place to hold and treat terrorists after October 7 has morphed into a harsh detention center with too little accountability.

The military denies the allegations of inhumane treatment and says all detainees needing medical attention receive it.

The hospital is near the city of Beersheba in southern Israel. It opened beside a detention center on a military base after the October 7 Hamas attack on Israel in which some 1,200 people, mostly civilians, were murdered and 252 were taken hostage because some civilian hospitals refused to treat wounded terrorists who took part in the atrocities. Of the three workers interviewed by AP, two spoke on condition of anonymity because they feared government retribution and public rebuke.

“We are condemned by the left because we are not fulfilling ethical issues,” said Dr. Yoel Donchin, an anesthesiologist who has worked at the Sde Teiman hospital since its earliest days. “We are condemned from the right because they think we are criminals for treating terrorists.”

The military this week said it formed a committee to investigate detention center conditions, but it was unclear if that included the hospital. Next week Israel’s highest court is set to hear arguments from human rights groups seeking to shut it down.

Israel has not granted journalists or the International Committee of the Red Cross access to the Sde Teiman facilities.

Israel has detained some 4,000 Palestinians since October 7, according to official figures, though roughly 1,500 were released after the military determined they were not affiliated with Hamas. Israeli human rights groups say the majority of detainees have at some point passed through Sde Teiman, the country’s largest detention center.

Doctors there say they have treated many who appeared to be non-combatants.

“Now we have patients that are not so young, sick patients with diabetes and high blood pressure,” said Donchin, the anesthesiologist.

A soldier who worked at the hospital recounted an elderly man who underwent surgery on his leg without pain medication. “He was screaming and shaking,” said the soldier.

Between medical treatments, the soldier said patients were housed in the detention center, where they were exposed to squalid conditions and their wounds often developed infections. There was a separate area where older people slept on thin mattresses under floodlights and a putrid smell hung in the air, he said.

The military said in a statement that all detainees are “reasonably suspected of being involved in terrorist activity.” It said they receive check-ups upon arrival and are transferred to the hospital when they require more serious treatment.

A medical worker who saw patients at the facility in the winter recounted teaching hospital workers how to wash wounds.

Donchin, who largely defended the facility against allegations of mistreatment but was critical of some of its practices, said most patients are diapered and not allowed to use the bathroom, shackled around their arms and legs and blindfolded.

“Their eyes are covered all the time. I don’t know what the security reason for this is,” he said.

The military disputed the accounts provided to AP, saying patients were handcuffed “in cases where the security risk requires it” and removed when they caused injury. Patients are rarely diapered, it said.

Dr. Michael Barilan, a professor at the Tel Aviv University Medical School who said he has spoken with over 15 hospital staff, disputed accounts of medical negligence. He said doctors are doing their best under difficult circumstances, and that the blindfolds originated out of a “fear [patients] would retaliate against those taking care of them.”

Days after October 7, roughly 100 Israelis clashed with police outside one of the country’s main hospitals in response to false rumors it was treating a terrorist.

In the aftermath, some hospitals refused to treat detainees, fearful that doing so could endanger staff and disrupt operations. They were already overwhelmed by people wounded during the Hamas attack and expecting casualties to rise from an impending ground invasion.

As Israel pulled in scores of wounded Palestinians to Sde Teiman, it became clear the facility’s infirmary was not large enough, according to Barilan. An adjacent field hospital was built from scratch.

The Health Ministry laid out plans for the hospital in a December memo obtained by AP.

It said patients would be treated while handcuffed and blindfolded. Doctors, drafted into service by the military, would be kept anonymous to protect their “safety, lives and well-being.” The ministry referred all questions to the military when reached for comment.

Still, an April report from Physicians for Human Rights-Israel, drawing on interviews with hospital workers, said doctors at the facility faced “ethical, professional and even emotional distress.” Barilan said turnover has been high.

Patients with more complicated injuries have been transferred from the field hospital to civilian hospitals, but it has been done covertly to avoid arousing the public’s attention, Barilan said. And the process is fraught: The medical worker who spoke with AP said one detainee with a gunshot wound was discharged prematurely from a civilian hospital to Sde Teiman within hours of being treated, endangering his life.

The field hospital is overseen by military and health officials, but Donchin said parts of its operations are managed by KLP, a private logistics and security company whose website says it specializes in “high-risk environments.” The company did not respond to a request for comment.

Because it’s not under the same command as the military’s medical corps, the field hospital is not subject to Israel’s Patients Rights Act, according to Physicians for Human Rights-Israel.

A group from the Israeli Medical Association visited the hospital earlier this year but kept its findings private. The association did not respond to requests for comment.

The military told AP that 36 people from Gaza have died in Israel’s detention centers since October 7, some of them because of illnesses or wounds sustained in the war. Physicians for Human Rights-Israel has alleged that some died from medical negligence.

Khaled Hammouda, a surgeon from Gaza, spent 22 days at one of Israel’s detention centers. He does not know where he was taken because he was blindfolded while he was transported. But he said he recognized a picture of Sde Teiman and said he saw at least one detainee, a prominent Gaza doctor who is believed to have been there.

Hammouda recalled asking a soldier if a pale 18-year-old who appeared to be suffering from internal bleeding could be taken to a doctor. The soldier took the teenager away, gave him intravenous fluids for a few hours, and then returned him.

“I told them, ‘He could die,'” Hammouda said. “‘They told me this is the limit.’”
