Palestinian refugee Ibrahim Abu Mustaf (R), 83, who says is a former inhabitant of the town of Beersheva, sits next to his wife Amna, 75, outside his home in the Khan Yunis refugee camp in the southern Gaza Strip on May 15, 2016, on the 68th anniversary of the "Nakba". "Nakba" means in Arabic "catastrophe" in reference to the birth of the state of Israel 68-years-ago in British-mandate Palestine, which led to the displacement of hundreds of thousands of Palestinians who either fled or were driven out of their homes during the 1948 war over Israel's creation. The key symbolises the homes left by Palestinians in 1948. (AFP PHOTO / SAID KHATIB)
