The U.N.'s top anti-torture envoy in Geneva announced he is reviewing a complaint filed on behalf of Pfc. Bradley Manning, the 23-year-old soldier accused of leaking a trove of documents and classified military video to WikiLeaks. The complaint alleged that Manning's conditions in prison, where he is being held in solitary confinement 23 hours a day and forced to speak every five minutes, amount to torture. The Pentagon denies mistreating Manning, who is being held until he is court-martialed, but media organizations have reported that the private's health is deteriorating, and several psychologists and torture experts have argued that Manning's solitary confinement and sensory deprivation constitute torture. WikiLeaks founder Julian Assange has called on human rights organizations to investigate the situation, but maintains that he had never heard of Manning before his name began appearing in news stories.
