I thought the Bedouin hated the Arabs.
Beduins are Arabs - of the indigenous desert tribes. In their culture, they tend to look down upon villagers and city Arabs as lesser beings. But this is just a cultural prejudice, and usually not taken seriously.
However, there is a recent and bitter illfeeling between the Beduin of the Sinai and the Egyptian police. They say the police have been brutal to them. The police say that the Beduin are involved in people smuggling and illegal trade over the Israeli border.
