By attacking the Eastern Province, IS seeks to place Riyadh in the position of defending or appeasing Shiites, at the expense of a Saudi Wahhabist state ideology that does not tread too far from that of IS (e.g., Saudi schools teach students that Shiites are unbelievers and not Muslims). In that sense, the group likely considers Riyadh’s actions following the first attack a victory.
In response to the May 22 suicide bombing in Qatif, Saudi Interior Ministry spokesman Maj. Gen. Mansour al-Turki stated that the goal of IS was to spread sectarianism, while Crown Prince Muhammad bin Nayef visited the town and gave condolences to the victims and their family members. Moreover, Grand Mufti Abdul Aziz ibn Abdullah al-Sheikh condemned the “criminal plot.” From the Islamic State’s perspective, such actions highlight Riyadh’s rank hypocrisy, showing “true” believers in the “land of the two holy places” how the Saudi state is contravening both God and its own founding standards. By casting themselves as the true bearers of Islam, IS leaders hope to draw more recruits and supporters.
