The younger brother of Mohamedou Ould Slahi, Yahdih Ould Slahi poses with a copy of Mohamedou's prison memoir 'Guantanamo Diary' open to show pages that were redacted by the US government in London on January 20, 2015. The family and supporters of "one of the most abused prisoners in Guantanamo" on January 20 launched a new celebrity-backed campaign demanding his release, coinciding with the publication of his prison diary. Mohamedou Ould Slahi was detained in his home country of Mauritania following the September 11 attacks on the United States in 2001, on suspicion of involvement in an unsuccessful plot to bomb Los Angeles in 1999, and was taken to Guantanamo in 2002. US district court judge James Robertson ordered that Slahi be released in 2010 due to lack of evidence that he was directly involved in al-Qaeda terror plots, but he remains in detention after the Department of Justice appealed the decision. Human rights activist Larry Siems, the book's editor, Slahi's lawyer Nancy Hollander and brother Yahdih described the battle to release the memoirs and his current legal limbo during a press conference in London.
