A veteran al Qaeda fighter, and an expert in document forgery who has decades of experience helping jihadists travel internationally without detection, has gone missing after being released from the detention facility at Guantanamo.

The Obama administration released the former detainee, Jihad Ahmed Mujstafa Diyab, in December 2014 to Uruguay, despite the fact that U.S. military and intelligence professionals had declared him a “high risk” detainee—one who was likely to return to terrorism if freed. According to a report by Public Radio International, authorities in Uruguay have “no idea” of Diyab’s current location. But they suspect that the detainee, who declared earlier this year “I like al Qaeda”, has left Uruguay for Brazil.
