Shown above are snapshots collected by the legal charity Reprieve of some of the men still being held at US detention facilities at Guantanamo Bay, Cuba.

Despite election campaign promises by Barack Obama, the US president, to shut down Guantanamo Bay, more than 200 people remain imprisoned. Of the 242 prisoners inherited from the Bush administration, only 11 have been released during Obama's first six months in office.

A number of the inmates still held at Guantanamo were cleared for release by the Bush administration, but Obama has since ordered a reassessment of all the prisoners' statuses.

Many of the prisoners have been held - some as long as seven years - without charge or trial.
