Souad Zohair, 73, has been kept alive by kidney dialysis three days a week at a hospital in Rafah, but that has been shut by Israel's latest offensive. Her daughter brought her up the dangerous coastal road to the last hospital left in the Gaza Strip that still has functioning dialysis machines.

In a crowded room, her blood was trickling through tubes from her hand into the machine. Today, she'll live.

"This is the only remaining hospital (for dialysis) serving the entire Gaza Strip, serving around 1,000 remaining patients with kidney failure," said Dr. Saeed Khattab, head of the kidney department at Al Aqsa Martyrs hospital in Deir al-Balah in central Gaza.
