United States President Barack Obama has approved a new elite team to question key terror suspects, at the same time as there have been new disclosures about CIA abuse of detainees.
The unit will be housed at the FBI headquarters in Washington and be overseen by the White House, the BBC reports.
A newly declassified report was released on Monday, detailing prisoner abuses by the CIA under the Bush administration, including and mock executions and agents threatening to kill a suspect's children.
The findings could lead to prosecutions of CIA employees.
The declassified document shows one agent told Khalid Sheikh Mohammed his children would be killed if there were further attacks on the US.
The report was prepared in 2004, but only a heavily censored version had been issued until now.
