Mr Mohammed appears with a long beard and wearing a white robe in the photos, taken in July by the Red Cross at the US detention centre in Cuba. Red Cross said it took the most recent photos in July and sent them to Mr Mohammed's family and were not intended for public release. But according to Jarret Brachman, former research director at the Combating Terrorism Center of the West Point US Military Academy the images have appeared in recent days on extremist websites.
President Barack Obama, who has said he wants to close the Guantanamo detention centre by January, kept Mr Mohammed's trial is currently on hold as it is yet to be decided on how to continue military prosecutions for some detainees.
