TEL AVIV, Israel - With the first three Israeli hostages freed in the cease-fire for hostages deal, Fox News Digital has exclusively learned that several terrorists captured by Israeli forces last month confessed that Israeli captives were held at different times at the Kamal Adwan Hospital in northern Gaza.

The Israeli Defense Forces (IDF) recently completed a major raid on the hospital, arresting some 240 terrorists. The director of the hospital, Hussam Abu Safiya, the Israelis claim, had gathered intelligence showing that he not only allowed Hamas to infiltrate the hospital, but actively collaborated with the terror group.

Another captured terrorist, Anas Muhammad Faiz al-Sharif, who worked at the hospital as a cleaning supervisor and joined the Nukhba forces of Hamas’s Al-Qassam Brigades in 2021, told Israeli interrogators that the northern Gaza facility was viewed as "a safe haven for them because the [Israeli] military cannot directly target it."

He revealed that inside the hospital, terrorists distributed grenades and mortars, along with equipment for ambushing IDF troops and tanks.

UN ACCUSED OF DOWNPLAYING HAMAS TERRORISTS’ USE OF GAZA HOSPITALS AS NEW REPORT IGNORES IMPORTANT DETAILS

Fox News Digital asked a World Health Organization (WHO) spokesman if, based on the IDF's new allegations about holding hostages at Adwan Hospital, they would condemn Hamas' use of hospitals for military use. 

In a statement, the spokesman said, "The International Humanitarian Law is very clear. Healthcare workers and healthcare facilities are off limits. They must not be attacked. They must not be used for military purposes. They must be protected at all times. The point is both to protect civilians, as well as to protect the health systems and infrastructure that communities depend on for life-giving care and continuity of services. 

"Failure to protect and respect healthcare devastates twice. First, in the initial harm, and then again for the months or years it takes to rebuild the health systems."

The statement concluded without condemning or singling out Hamas. "The protection of healthcare also includes the prohibition against combatants using health facilities for military purposes. IHL is also clear that even if healthcare facilities are being used for military purposes, there are stringent conditions which apply to taking action against them, including a duty to warn and to wait after warning and even then, disproportionate attacks are strictly prohibited."

Richard Goldberg, a senior adviser at the Foundation for Defense of Democracies and former Trump National Security Council official, claimed, "Several international organizations operating in Gaza likely had direct knowledge of Hamas using hospitals as terror headquarters and only publicly protested Israel’s attempt to clear the terrorists. The Red Cross, UNRWA, World Health Organization - they were all collaborators."

Goldberg offered advice for President Trump's pick for U.N. ambassador, Elise Stefanik, who goes before the Senate on Tuesday. "Stefanik would be fully justified in launching investigations into each of those agencies - demanding documents and personnel interviews. And if they don’t comply, they can deal with the consequences."

One of Trump's first acts on Monday was to withdraw the U.S. from the WHO. 

During the monthslong IDF operation in northern Gaza, more than 700 terrorists were detained, including Hamas commanders, some of whom participated in the Oct. 7, 2023, massacre in southern Israel. More than a dozen of those captured were involved in kidnapping or holding Israeli hostages in Gaza.

During the operation, the IDF located and destroyed thousands of weapons, including RPGs stashed within the hospital itself. The aim of the campaign was to completely defeat Hamas's Northern Brigade and remove the terror group's presence from within the civilian population. IDF troops conducted raids ranging from a few hours up to a full day. During the longer ones, they entered the hospital and searched for weapons and terrorists.

Former Shin Bet agent Gonen Ben Itzhak, who was the handler of former Hamas informant Mosab Hassan Yousef, the son of a Hamas founder, told Fox News Digital that, "Using visual intelligence, it’s easy to see when Hamas brings guns and ammunition into the hospital … and even with one human source, you can get intel on what is happening inside. From a signal point of view, the terrorists use phones and walkie-talkies, which can be intercepted."

WORLD HEALTH ORGANIZATION SILENT OVER HAMAS’ USE OF GAZA HOSPITAL AS TERROR HQ 

Almost no fighting took place inside the hospital, from which some 950 people were eventually evacuated, all before the IDF's final raid. Since then, the Israeli military has facilitated and secured the transfer of the hospital's operations to the nearby Indonesian Hospital, at the request of the Palestinians.

Even as the United Nations and the international community condemned Jerusalem for its anti-terrorism campaign at Kamal Adwan, a former Palestinian Authority official, told Fox News Digital that Hamas’ use of hospitals was "immoral" and known to endanger patients and health workers.

Adnan al-Damiri recently went viral on social media after the Israel-based Palestinian Media Watch organization flagged his Facebook post showing that Hamas had summoned a Gazan reporter for questioning to Nasser Hospital in Khan Younis in the southern Strip.

"I made this post to show Palestinians that Hamas is doing everything against the people of Gaza, including in hospitals. Hamas claims its struggle is against the [Israeli] occupation, but the fact is they use our people," al-Damiri said. He noted that the document posted to social media was sent to him by a friend of the Gazan who was summoned for interrogation.

"I know that it’s a real document. I am not afraid of Hamas," he added.

CEASE-FIRE BETWEEN ISRAEL AND HAMAS GETTING CLOSER AMID CONCERNS TERROR GROUP REARMING IN GAZA

In December 2023, Ahmed Kahlout, then-director of Kamal Adwan Hospital, told his Israeli interrogators that he and other staff were Hamas operatives. Kahlout described how Hamas used ambulances to hide operatives, transport terrorist squads and deliver a kidnapped IDF soldier.

Basem Naim, a member of Hamas' political bureau in Gaza, told Fox News Digital that his "resistance movement understands very well the importance of respecting international humanitarian law and its obligations, and understands very well the needs of our people for civil services and the importance of protecting them.

"I can confidently say that Hamas hasn't used any hospital as a military base or a shelter for fighters," he continued. "Regarding all the aggressions against hospitals in the Gaza Strip, Israel wasn’t able in any case to prove or to give serious or neutral evidence for its claims," he said. 

"We call for the immediate release of Dr. Abu Safiya, director of Kamal Adwan Hospital, who was kidnapped by Israeli forces, with dozens of other medics. Israel is fully responsible and accountable for their lives. Dr. Safiya isn't a Hamas member," added Naim.

A month after Hamas’ Oct. 7, 2023 massacre, the IDF already began publishing evidence of Hamas's use of hospitals, in particular, for terror purposes. In one recording from November 2023, a Gaza health official can be heard confirming that Hamas had stored more than half a million liters (over 132,000 gallons) of fuel under Shifa Hospital, the Strip’s largest medical center.

Hamas was accused of systematically turning Shifa into a major command center and even storing weapons in the MRI building. On Nov. 19, 2023, the IDF released surveillance footage of armed terrorists bringing hostages into Shifa. The IDF discovered the remains of two Israeli hostages, Noa Marciano and Yehudit Weiss, in the vicinity of Shifa last year.
