The World Health Organization said Tuesday that it has helped to successfully transfer 32 critically ill patients, including two children, from besieged Nasser Hospital in the southern Gaza Strip.

The WHO said its staff led two "life-saving," "high-risk" missions at the medical complex in Khan Younis on Sunday and Monday, in close partnership with the Palestine Red Crescent Society and the United Nations Office for the Coordination of Humanitarian Affairs, "amid ongoing hostilities and access restrictions." Staff at Nasser Hospital had requested the transfer of patients after the facility became "non-functional" following an Israeli military raid on Feb. 14 after a weeklong siege, according to the WHO.

"Weak and frail patients were transferred amidst active conflict near the aid convoy," the WHO said in a statement. "Road conditions hindered the swift movement of ambulances, placing the health of patients at further risk."

"Nasser Hospital has no electricity or running water, and medical waste and garbage are creating a breeding ground for disease," the organization added. "WHO staff said the destruction around the hospital was 'indescribable.' The area was surrounded by burnt and destroyed buildings, heavy layers of debris, with no stretch of intact road."

The WHO estimates that 130 sick and injured patients and at least 15 doctors and nurses remain inside Nasser Hospital. As the facility's intensive care unit was no longer functioning, the only remaining ICU patient was transferred to a different part of the complex where other patients are receiving basic care, according to the WHO.

"WHO fears for the safety and well-being of the patients and health workers remaining in the hospital and warns that further disruption to lifesaving care for the sick and injured would lead to more deaths," the organization said. "Efforts to facilitate further patient referrals amidst the ongoing hostilities are in process."

Prior to the missions on Sunday and Monday, the WHO said it "received two consecutive denials to access the hospital for medical assessment, causing delays in urgently needed patient referral." At least five patients reportedly died in Nasser Hospital's ICU before any missions or transfers were possible, according to the WHO.

Nasser Hospital is the main medical center serving southern Gaza. Ground troops from the Israel Defense Forces stormed the facility last week, looking for members of Hamas who the IDF alleges have been conducting military operations out of the hospital. Hamas, the Palestinian militant group that governs Gaza and is at war with neighboring Israel, denies the claims.

"The dismantling and degradation of the Nasser Medical Complex is a massive blow to Gaza's health system," the WHO said. "Facilities in the south are already operating well beyond maximum capacity and are barely able to receive more patients."

A new analysis by the Global Nutrition Cluster, a humanitarian aid partnership led by the United Nations International Children's Emergency Fund, found that 90% of children under the age of 2 in the war-torn Gaza Strip face severe food poverty, meaning they eat two or fewer food groups a day.

The same was true for 95% of pregnant and breastfeeding women in Gaza, according to the report released Monday. And at least 90% of children under 5 are affected by one or more infectious disease, with 70% experiencing diarrhea in the past two weeks, the report said.

In Gaza's southernmost city of Rafah, where most humanitarian aid enters, 5% of children under 2 are acutely malnourished, compared to more than 15% in northern Gaza, which has been isolated by the Israeli military and almost completely cut off from aid for weeks, the report said. Before war broke out last October between Israel and Gaza's militant rulers, Hamas, the acute malnutrition rate across the coastal enclave was less than 1%, according to the report.

The report also found that more than 80% of homes in Gaza lack clean and safe water, with the average household having one liter per person per day.

"The Gaza Strip is poised to witness an explosion in preventable child deaths which would compound the already unbearable level of child deaths in Gaza," Ted Chaiban, deputy executive director for humanitarian action and supply operations at UNICEF, said in a statement. "We've been warning for weeks that the Gaza Strip is on the brink of a nutrition crisis. If the conflict doesn't end now, children’s nutrition will continue to plummet, leading to preventable deaths or health issues which will affect the children of Gaza for the rest of their lives and have potential intergenerational consequences."

Israeli troops have turned Nasser Hospital, the main medical center serving the southern Gaza Strip, into a "military barracks" and are "endangering the lives of patients and medical staff," according to Gaza's Hamas-run Ministry of Health.

The health ministry said Monday that patients and medical staff inside Nasser Hospital are now without electricity, water, food, oxygen and treatment capabilities for difficult cases since Israeli ground troops raided the facility in the southern Gaza city of Khan Younis last week.

The World Health Organization, which warned on Sunday that Nasser Hospital "is not functional anymore," said more than 180 patients and 15 doctors and nurses remain inside the hospital.

The WHO said it has evacuated 14 critical patients from the hospital to receive treatment elsewhere.

The Israel Defense Forces alleges that Hamas, the Palestinian militant group that governs Gaza, has been conducting military operations out of Nasser Hospital and other medical centers in the war-torn enclave -- claims which Hamas denies.

The Israel Defense Forces said its fighter jets hit two Hezbollah weapons storage facilities in Lebanon on Monday.

The IDF said this was in response to the unmanned aerial vehicle launched toward northern Israel earlier in the day, and the Israelis believe it was most likely launched from Lebanon by Hezbollah.

The IDF also said its fighter jets have struck some Hezbollah terrorist infrastructure in Lebanon on Monday.

Eight patients who died because of a lack of electricity at Nasser Medical Complex in Gaza are still in their beds inside of the hospital among living patients, the Hamas-run Gaza Ministry of Health said Wednesday.

The Ministry of Health said the bodies are still in the hospital because Israeli forces refuse to remove them.

The bodies "have begun to swell and show signs of decomposition, posing a danger to other patients," the Ministry of Health said in a statement.

Israeli authorities denied these claims and said no bodies are still inside Nasser Hospital.

The Israel Defense Forces has been operating inside of Nasser Hospital for the last week. On Monday, the IDF announced its soldiers had arrested 200 suspected Hamas members at Nasser Hospital.
