Mohammed Al Ansi was one of ten Guantanamo detainees transferred to Oman earlier this week. Ansi had been denied transfer as recently as March 2016. The US government found that he “participated in advanced combat training and may have met with al Qaeda external operations chief Khalid Shaykh Mohammed.” Ansi may have been “considered for participation in a suicide attack or deployment in the West” as part of the 9/11 hijackings.
Earlier this month, a review board responsible for evaluating the status of Guantanamo detainees determined that a Yemeni held in Cuba since early 2002 should remain in custody. According to a leaked threat assessment, the detainee was slated to be a hijacker on 9/11 before al Qaeda canceled his part of the operation.
