I first met Dr Izeldeen Abuelaish eight years ago when I made a radio documentary about his extraordinary life and work. A Palestinian obstetrician who specialises in treating infertility, he lives in the Jabaliya camp in the Gaza Strip, but used to work part-time in Israel helping Jewish women to have babies. He also had a clinic in Gaza, taught medical school students there and arranged for seriously ill Palestinian patients to be treated in Israel.
