DEIR AL-BALAH, Gaza Strip (Reuters) - Souad Zohair, 73, has been kept alive by kidney dialysis three days a week at a hospital in Rafah, but that's shut now by Israel's latest offensive. "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.
