UNRWA was set up in 1949, following the establishment of the state of Israel. It has accused Hamas of trying to moderate itself to work with the USA -backed Palestinian faction Fatah, in order to appeal to the West.

Since then, the group has overpowered smaller militant factions close to al-Qaida and has become the most brutal jihadist group in Egypt.
