Dr Nidal Abed works in a hospital in Gaza. He treats patients wherever he can, — on the floor, in the corridors, in rooms crammed with 10 patients instead of two, and however he can – using clothes for bandages, vinegar for antiseptic, sewing needles for surgical ones. The only thing worse than the screams of a patient undergoing surgery without enough anaesthesia are the terror-stricken faces of those awaiting their turn, the 51-year-old orthopedic surgeon says.
