Despite being prepared for the worst, an international team of doctors was left speechless by the toll Israel's brutal war has had on Gazan children.

One toddler died from a brain injury caused by an Israeli strike that fractured his skull. His cousin, an infant, is still fighting for her life with part of her face blown off by the same strike.

An unrelated 10-year-old boy screamed out in pain for his parents, not knowing that they were killed in the strike. Beside him was his sister, but he didn’t recognize her because burns covered almost her entire body.

These gut-wrenching casualties were described to The Associated Press (AP) by Tanya Haj-Hassan, a pediatric intensive-care doctor from Jordan, following a 10-hour overnight shift at Al-Aqsa Martyrs Hospital in the town of Deir al-Balah.

Haj-Hassan, who has extensive experience in Gaza and regularly speaks out about the war’s devastating effects, was part of a team that recently finished a two-week stint there.

After nearly six months of Israeli aggression, Gaza’s health sector has been decimated. Roughly a dozen of Gaza’s 36 hospitals are only partially functioning. The rest have either shut down or are barely functioning after they ran out of fuel and medicine, were surrounded and raided by Israeli troops, or were damaged in fighting.

That leaves hospitals such as Al-Aqsa Martyrs caring for an overwhelming number of patients with limited supplies and staff. The majority of its intensive care unit beds are occupied by children, including infants wrapped in bandages and wearing oxygen masks.

"I spend most of my time here resuscitating children," Haj-Hassan said after a recent shift. "What does that tell you about every other hospital in the Gaza Strip?"

A different team of international doctors working at Al-Aqsa Martyrs in January stayed at a nearby guesthouse. But because of a recent surge of Israeli Israel strikes nearby, Haj-Hassan and her co-workers stayed in the hospital itself.

That gave them a painfully vivid look at the strain the hospital has come under as the number of patients keeps rising, said Arvind Das, the team leader in Gaza for the International Rescue Committee. His organization and Medical Aid for Palestinians organized the visit by Haj-Hassan and others.

Mustafa Abu Qassim, a nurse from Jordan who was part of the visiting team, said he was shocked by the overcrowding.

"When we look for patients, there are no rooms," he said. "They are in the corridors on a bed, a mattress, or on a blanket on the floor."

"Just miserable"

Before the war, the hospital had a capacity of around 160 beds, according to the World Health Organization. Now there are some 800 patients, yet many of the hospital's 120 staff members are no longer able to come to work.

Health care workers face the same daily struggle as others in Gaza in finding food for their families and trying to ensure some safety for them. Many bring their children with them to the hospital to keep them close, Abu Qassim said.

"It’s just miserable," he added.

Thousands of people driven from their homes by the war are also living on the hospital grounds, hoping it will be safe. Hospitals have special protections under international law, though those protections can be removed if combatants use them for military purposes.

Israel has alleged that hospitals serve as command centers, weapons storage facilities and hideouts for Hamas, but has presented little visual evidence. Hamas has denied the allegations. Israel has been carrying out a large-scale operation in Gaza's largest hospital, Al-Shifa, for the past week.

Israeli troops have not raided or besieged Al-Aqsa Martyrs but have attacked surrounding areas, sometimes striking close to the hospital. In January, many doctors, patients, and displaced Palestinians fled the hospital after a flurry of strikes.

Israel’s bombardment and offensive in Gaza have killed more than 32,000 Palestinians, mostly women and children, and wounded nearly 75,000 more in the territory of 2.3 million people, according to Gaza’s Health Ministry.

Roughly half of Gaza's 2.3 million people are 17 or younger, the U.N.'s agency for children estimates.

Israel claims one-third of the dead are Hamas members but has not backed up the claim with evidence.

The war was triggered by the Oct. 7 Hamas incursion of southern Israel, killing around 1,160 people and taking some 250 hostages. The Israeli government believes around 100 hostages being held in Gaza are still alive.

In the early stages of the war, Israel severely limited the entry of food, fuel and medical supplies into Gaza. Israel claims there are no longer any limits but the international community has called on Israel to let in more.

Aid groups say complicated inspection procedures at the border, continued fighting, and a breakdown in public order have caused massive slowdowns in convoys. Israel accuses the U.N. of disorganization.

The result has been catastrophic, with hospital staff struggling to cope with a shortage of spare parts to maintain medical equipment. Al-Aqsa Martyrs has also been short on anesthetics, meaning surgeries and other procedures are frequently performed without painkillers.

Haj-Hassan says there is only one way to end Gaza’s health care crisis.

"They need the war to stop," she said.
