Trafficking and the Role of the Sinai Bedouin
On the evening of October 7, 2004, three trucks laden with explosives were driven to resorts in the northern Sinai where they were detonated, killing more than 30 people and wounding hundreds more. The targets were Israelis vacationing during their High Holidays at the usually tranquil desert oases of Taba, Ras al-Sultan and Tarabeen. At least three previously unknown terrorist organizations claimed responsibility for the terrorist incident; however, the leading suspect and group named by the Egyptian government was al-Tawhid Wal-Jihad ("Monotheism and Struggle"), comprised of Bedouin tribesmen from the Sinai Peninsula. The Taba attacks marked the first time that Bedouins from the Sinai were implicated in acts of terrorism on Egyptian soil.

Activities targeting Israel have sometimes been ignored by the Egyptians, unlike the scenes of mass arrests and shootouts between Egyptian security forces and Bedouin tribesmen that have plagued the region since the attacks in the Sinai Peninsula.
