The Ministry of Defence has said it is investigating 33 new allegations of abuse by the UK military in Iraq.
Lawyers acting for former Iraqi detainees are calling for a full public inquiry into all abuse claims made during UK military involvement there.
Iraqi human rights campaigner Mazin Younis, who has been collating and documenting the stories of alleged victims of abuse, explained the allegations to Today presenter Evan Davis.
He said cases of serious sexual and violent abuse in Iraq were widespread, but that people were only coming forward now because they were too scared of the British forces when they were in the country.
Minister for the Armed Forces Bill Rammell responded to the allegations, saying that while allegation of abuse were taken with the "utmost seriousness", there was no evidence of endemic abuse within the armed forces.
