Every year Palestinians commemorate the Nakba ("the catastrophe"): the expulsion and dispossession of hundreds of thousands Palestinians from their homes and land in 1948. In 1948 more than 60 percent of the total Palestinian population was expelled. More than 530 Palestinian villages were depopulated and completely destroyed.
To date, Israel has prevented the return of approximately six million Palestinian refugees, who have either been expelled or displaced. Approximately 250,000 internally displaced Palestinian second-class citizens of Israel are prevented from returning to their homes and villages.
