The Tawhid Islamic Brigades have only been associated with one attack in their history. On October 7, 2004, three nearly-simultaneous car bombings occurred in the Sinai Peninsula, killing 36 and injuring 171. Egyptian authorities stated that Egyptian-born Palestinians, Ayad Said Saleh and Suleiman Ahmed Saleh Flayfil were responsible for the suicide car bombing that killed 34 and injured 159 at a Hilton Hotel in Taba. The other two car bombs were detonated remotely in campgrounds in Ras al-Shitan by Hammad Gaman Gomah and Mohamed Ahmed Saleh Flayfil, the brother of Suleiman Ahmed Saleh Flayfil. Thus far, both of these men have managed to avoid capture. A spokesperson for the Egyptian government speculated that these attacks were carried out in response to an Israeli offensive in Gaza that killed 84 Palestinians. <br /><p><br /><br />Three terrorist organizations claimed responsibility for this attack, two of which were previously unknown (the Tawhid Islamic Brigades and Jammaa Islamiya) and one of which is a fairly well established group with known ties to al-Qaeda (the Battalions of the Martyr Abdullah Azzam, al-Qaeda in the Levant and Egypt). Though all three claims neglected to give details about how the attacks were carried out, a common feature of most legitimate claims, the Tawhid Islamic Brigades' claim is most interesting because it correctly identifies that four men were involved in the attack.<br /><p><br /><br />The Tawhid Islamic Brigades' claim was announced on a website normally used for claims originating from Saudi Arabia and Iraq, fueling suspicion that the group has ties with Abu Musab al-Zarqawi's Tawhid and Jihad and its successor organization, al-Qaeda Organization in the Land of the Two Rivers, which seeks to create an Islamic state in Iraq. Zarqawi, like the men who were behind the Sinai attacks, is Palestinian. <br />

Since the Sinai attacks, this organization has neither claimed nor been implicated in any terrorist activity. It is likely that Tawhid Islamic Brigades is an alias for another group or the name of a small group with close ties to larger organizations.
