Oscars tribute to torture victim

Tributes have been paid at the Oscars award ceremony in Hollywood to a young Afghan taxi driver who died in US military detention.

The American director, Alex Gibney, who won Best Documentary for Taxi to the Dark Side, dedicated his film to the 22-year-old driver, Dilawar.

His death at a prison in Afghanistan in 2002 provided the basis for the film.

A leaked US military report later found that his mistreatment continued after interrogators decided he was innocent.

The film examines the interrogation techniques used by American forces.
