When I visited Egypt, there were about 100 Jews praying there on Saturday morning. I understand that many of these were, as I was, Jews visiting areas where their ancestors had lived. Most of the 80,000 Egyptian Jews who lived in Cairo before 1947 were driven out with only the clothes on their backs. The few remaining are very old. Sunday is not a day of worship for Jews in general and so there would not have been many there. I would suppose that is why there were no casualties.
