Omar Khadr, a Canadian-born prisoner at Guantanamo Bay, has pleaded guilty to all terrorism charges in a tribunal.
Khadr pleaded guilty to five charges, including murder, in a plea agreement with military authorities.
Details of the plea deal have not yet been disclosed.
The 24-year-old, who had been facing a possible life sentence if convicted, was captured in Afghanistan in 2002 when he was 15.
Authorities will now hold a sentencing hearing before a jury of military officers.
Khadr's lawyers have argued in the past that his family forced him into the war as a child.
His trial began in August but was delayed when his lawyer fell ill.
Khadr is the youngest detainee at Guantanamo.
