Razan al-Najjar was the 21-year-old Palestinian medical nurse shot dead by an Israeli sniper during protests. To her parents she was a beloved daughter who died just a few hundred meters from her home in Khan Younis, close to the fence that separates Gaza from Israel. 1000's took to the streets of the Gazan city for the medic's funeral. The streets and lampposts surrounding Razan's home are now adorned with her smiling image. Her father, Ashraf al-Najjar, takes CNN up three flights of stairs and into their apartment. The rest of the family, their small home now filled with mourners, sit in disbelief.
