Palestinians hold a large key, symbolising the homes left by Palestinians in 1948, during a rally to commemorate the 68th anniversary of Nakba, meaning catastrophe, the day when the state of Israel was created, in the West Bank city of Nablus, on May 15, 2016. Since 1948, the Palestinians all over the world mark Nakba on May 15. According to the Palestinian Statistics Bureau Center, 957,000 Palestinians left their homes in towns, cities and villages in 1948, which represents 66 percent of the total number of Palestinians who lived in historic Palestine at that time.
