Iraq has launched an investigation into claims by the US military that an Iraqi interior ministry "death squad" has been targeting Sunni Arab Iraqis.
The probe comes after a US general revealed the arrest of 22 policemen allegedly on a mission to kill a Sunni.

"We have found one of the death squads. They are part of the police force," US Maj Gen Joseph Peterson said.

Sunnis have long accused Iraqi forces of operating death squads - but the claims have never been substantiated.

Iraqi deputy interior minister Maj Gen Hussein Kamal said his ministry had set up an inquiry.
