If you have a chance, watch this video about the Palestinian Refugees that was made in 1950.
Sands of Sorrow
It is filmed in Gaza. Of note is that there are no veils on the women and they seemed fully integrated into the camp society. Another item that struck me was that only one out of five newborns survived. Little is made of the Muslim religion except to mention that prayer was a part of the culture. By necessity, I suspect, there was no mention of why the refugee problem existed. The commentator does mention that the refugees fully expected to return to their homes, and this was why they brought little with them.
Many of the children in the film will be in their sixties, if they survived. I wonder how they feel watching this film.
