Ahmed Ressam
Guantanamo DiaryAhmed Ressam enters the account as both a participant in the Millennium Plot and an absent link in the case against Mohamedou Ould Slahi. An Algerian immigrant and al-Qaeda member, he was arrested while attempting to enter the United States in a car carrying explosives, with a plan to bomb Los Angeles International Airport on New Year’s Day. His connections to Montreal and its al Sunnah mosque helped draw investigators’ attention to Slahi, who had arrived in the city after Ressam had left. Yet Ressam’s later cooperation with authorities produced extensive testimony and intelligence without implicating Slahi. That gap gives Ressam significance beyond his own criminal case: his name helped generate suspicion around Slahi, while the record of what Ressam actually said undercut a central avenue for connecting Slahi to terrorism.
Background and Montreal Connections
Ressam was based in Montreal and had attended the city’s al Sunnah mosque. Slahi moved to Montreal in November 1999, after being unable to obtain permanent residency in Germany. He lived first with a former classmate and later at the mosque, where he was invited to lead Ramadan prayers when the imam was away. Ressam had left Montreal before Slahi arrived, so their shared association with the mosque did not establish that they knew one another.
The connection nevertheless had immediate consequences. Ressam’s arrest prompted a major investigation of Montreal’s Muslim immigrant community, particularly the al Sunnah mosque community. Slahi was questioned about possible terrorist connections for the first time in his life. He told investigators that he did not know Ressam, and later described the questioning as frightening and unfamiliar. The mosque thus became a point of overlap in the authorities’ inquiries, but the available account distinguishes that shared setting from evidence of a personal relationship between the two men.
The book’s editorial notes preserve uncertainty about other apparent references to Ressam. In one passage, the question posed to Slahi may refer to Ressam; another footnote says a reference appears to be to him. These identifications are presented as contextual judgments, not as recovered words from the censored manuscript. The distinction matters: the notes offer a plausible way to read redacted or ambiguous passages without claiming to restore text that remains unavailable.
The Millennium Plot and Cooperation
Ressam’s arrest concerned a plan to bomb Los Angeles International Airport on New Year’s Day, later called the Millennium Plot. The case brought him into cooperation with U.S. authorities. After entering a guilty plea and before sentencing, he began cooperating in exchange for assurances of a reduced sentence. Over roughly two years, he gave 65 hours of trial and deposition testimony and 205 hours of proffers and debriefings, provided information to seven governments, and testified in two trials that ended in convictions. He named at least 150 people involved in terrorism and supplied information about explosives that potentially helped protect law-enforcement agents.
The scale of that cooperation makes the omission of Slahi especially consequential. Ressam did not name or implicate him in those sessions. The account notes that Ressam’s information was used by the U.S. government as evidence against some other Guantanamo detainees in their habeas cases, but not against Slahi. A later court of appeals account also records that Ressam recanted some of his testimony implicating other people in the Millennium Plot. The book does not turn that recantation into evidence about Slahi; rather, it keeps the distinction between Ressam’s statements about others and the absence of any accusation against Slahi.
Consequences for Slahi’s Case
Slahi told an administrative review board that the focus of his questioning in Mauritania and Jordan had been his alleged part in the Millennium Plot. His account places that line of inquiry before the later allegation connecting him to the September 11 attacks. By the time the CIA took Slahi to Jordan, however, Ressam had already been cooperating for months. By the time the CIA retrieved Slahi eight months later, Ressam had testified in two terrorism trials and provided names to multiple governments. The available record therefore made Ressam’s failure to implicate Slahi difficult to dismiss as the result of a brief or limited inquiry.
In reviewing Slahi’s habeas case, Judge James Robertson noted that Ressam conspicuously failed to implicate him. The government had initially argued that Slahi could be detained under the theory that he had aided the September 11 attacks, but later abandoned that argument, acknowledging that he probably did not know about the attacks. These facts do not establish what Ressam knew beyond the record described in the book. They do show why his cooperation matters: a prolific source whose information reached investigators and courts did not supply the alleged connection to Slahi.
Ressam’s role consequently has two sharply different faces in the narrative. His arrest helped place Slahi’s mosque and Montreal associations under suspicion; his subsequent statements, despite their breadth and use in other cases, did not connect Slahi to the Millennium Plot. The contrast exposes the distance between being scrutinized through proximity and being implicated by evidence. It also gives the narrative a concrete measure against which claims about Slahi’s supposed terrorist role can be assessed.
