As the U.N. secretary-general repeats his call for an immediate ceasefire, the death toll in Gaza has topped 10,000, including 4,000 children. We speak to an American doctor who just left Gaza and the founder of the Palestine Children’s Relief Fund, which runs the only pediatric cancer unit in Gaza. Israel has just ordered the hospital with the unit to be fully evacuated. “They’re not getting care right now because their hospitals are under attack,” says PCRF founder Steve Sosebee, who describes medical workers trying to evacuate to Egypt or continuing to provide care while sheltering in the hospital. “We can’t heal their bodies until this conflict stops.” Dr. Barbara Zind, a pediatrician who arrived in Gaza to support the PCRF a day before the Hamas attack, describes finding shelter and rationing food and clean water. After nearly a month trapped in Gaza, she was finally evacuated through the Rafah border crossing and arrived back home on Monday.
