The Israel Defense Forces said Sunday that boxes of medicine intended for Israeli hostages, a large number of weapons and a vehicle belonging to a kibbutz that was attacked by Hamas terrorists on Oct. 7 were found during a raid at Nasser Hospital in the southern Gaza Strip.

The IDF said its soldiers located "medicines specifically designated for the Israeli hostages in Gaza, large quantities of weapons and a vehicle belonging to Kibbutz Nir Oz" during its operations in Nasser Hospital in the city of Khan Younis.

The IDF said it also apprehended "hundreds of terrorists and other suspects who were hiding in the Nasser Hospital, some posing as medical staff."

"Boxes of medicine were found with the names of Israeli hostages on them. The packages of medicine that were found were sealed and had not been transferred to the hostages," the IDF said.

Brazilian President Luiz Inacio Lula da Silva has prompted the fury of Israeli officials by comparing Israel's war against Hamas terrorists in the Gaza Strip to the Nazi genocide during World War II.

"What is happening in the Gaza Strip with the Palestinian people has no parallel in other historical moments. In fact, it did exist when Hitler decided to kill the Jews," Lula said at a news conference Sunday at the 37th African Union Summit in Addis Ababa.

Lula also condemned the suspension of humanitarian aid to the U.N. Relief and Works Agency in Gaza, calling for an investigation into what he described as "genocide."

"It's not a war between soldiers and soldiers. It's a war between a highly prepared army and women and children," Lula said.

The UNRWA is facing criticism and financial strain after Israel claimed 12 of the group's staff members in Gaza were implicated in Hamas' Oct. 7 attack on Israel. The allegations prompted the United States, Germany, the European Union and other countries to suspend funding for the UNRWA.

Lula's comments led to a swift and angry response from Israeli President Benjamin Netanyahu, who issued a statement calling Lula's remarks "disgraceful and grave." Netanyahu condemned Lula for "this trivialization of the Holocaust."

"Drawing comparisons between Israel and the Nazis and Hitler is to cross a red line," Netanyahu said, adding in a separate statement that Lula "has disgraced the memory of the 6 million Jews murdered by the Nazis, and demonized the Jewish state like the most virulent anti-Semite."

Nasser Hospital "is not functional anymore" after Israeli forces raided the facility in the southern Gaza Strip on Thursday, the head of the World Health Organization said.

Dr. Tedros Adhanom Ghebreyesus, the head of the U.N. health agency, said a WHO team was not allowed to enter the facility in the city of Khan Younis on Friday or Saturday "to assess the conditions of the patients and critical medical needs, despite reaching the hospital compound to deliver fuel alongside partners."

There are still about 200 patients in the hospital, including 20 who need urgent referrals to other hospitals, the WHO chief said in a statement on X.

Israel says it has apprehended about 100 suspected terrorists in the hospital, including 20 who it says participated in Hamas' Oct. 7 attack. The military says it is looking for the remains of hostages inside the facility and does not target doctors or patients.

Gaza’s Health Ministry said a large number of medical staff were arrested by the Israel Defense Forces that turned the facility into military barracks. The facility is Gaza's largest remaining operating hospital and the strip's second-largest hospital.

The U.S. believes Israel is still "acting in good faith" on hostage negotiations, State Department spokesperson Matt Miller told reporters during a press briefing on Tuesday.

Miller was mostly tight-lipped on the latest round of discussions with Egypt, the U.S. and Qatar in Cairo, though he did say that the U.S. assesses that Israel still shares the administration's interest in reaching an agreement despite its potentially looming Rafah offensive and reports of the country's limited involvement in the talks.

"We have seen public statements from the government of Israel that they want to secure the release of hostages," Miller said.

Prime Minister Benjamin Netanyahu also reiterated to Secretary Antony Blinken last week in Israel that it is a "top priority" for him to secure the release of the hostages, Miller continued.

"So yes, we do believe they're acting in good faith," he said.
