An Islamic State suicide bomber struck the Shiite Imam Sadiq mosque in the center of Kuwait City June 26. On May 29, in Dammam, Saudi Arabia, another suicide bomber struck the entrance of a Shiite mosque just kilometers away from the site of a May 22 suicide bombing, also against a Shiite mosque, in the town of Qudaih, in the Shiite-majority Qatif province. That attack killed 21 and wounded more than 100.
IS may have chosen to target Kuwait as part of prior planning, but it is just as likely that the weak security coordination between Gulf countries has made Kuwait an alternative to the Shiite targets in Saudi Arabia, where security has been tightened.
