Yusef al-Ayeri, believed to be in charge of al-Qaeda operations in the Arabian peninsula, is shot and killed while attempting to flee a security checkpoint in Saudi Arabia. His body was strapped with explosives and a 6-month-old letter from Osama bin Laden was reportedly in his pocket. Al-Ayeri was publicly named earlier in the month and his photograph was distributed nationwide. [Knight Ridder, 6/4/2003] US intelligence had known of al-Ayeri by his alias “Swift Sword” for a year and had eventually learned his real name. They had told Saudi intelligence that he may be behind an aborted al-Qaeda plot to attack the US with a chemical bomb (see February-Late March 2003) and said they were highly interested in questioning him. However, not only is he killed, but the Saudis apparently never collect his personal effects, such as his cell phone, his address book, or his car registry, and never trace such clues back to any residence that can be searched. One CIA operative involved in the search to find him will later recall, “We wondered, was it an accident that they killed him, or not? The Saudis just shrugged.… The bottom line: the missing link [that could reveal who took part in the planned US attack] was dead and his personal effects, which can be pretty important, were gone. Like so much else when you’re dealing with these countries, you’re never sure—was it an issue of will or capability?” [Suskind, 2006, pp. 146, 237-239] The Internet communications run by al-Ayeri will be taken over by a previously unknown figure named Lewis Atiyallah. In 2005, it will be reported that some counterterrorism experts believe Atiyallah “is a pseudonym for Yusef al-Ayeri… Al-Ayeri was reported killed in 2003, however there are lingering doubts about whether he is in fact dead.” [AKI, 6/8/2005]
