A US military panel has found a woman soldier guilty of abusing prisoners at the Abu Ghraib jail, near the Iraqi capital Baghdad, in 2003.
England became the face of the scandal
Private Lynndie England, 22, appeared in some of the graphic photos of abuse at the prison which caused outrage.
The panel found her guilty on four counts of maltreating detainees, one count of conspiracy and one count of committing an indecent act.
England faces up to 10 years in prison when she is sentenced.
She was acquitted on a second conspiracy count.
No visible reaction
The panel in Texas rejected the defence argument that she had been led astray by her colleagues, in particular her then boyfriend, Specialist Charles Graner. He too has been convicted of prisoner abuse, and is serving 10 years in jail.

England was the last in a group of nine army reservists charged with mistreating inmates at the prison.
It took the panel of five military officers just two hours to reach their verdict.
England showed no visible reaction as she stood to attention in the military court, at Fort Hood, to hear the verdict.
A military prosecutor had argued that England had humiliated prisoners because she enjoyed it and had a sick sense of humour.
Prosecutor Chuck Neill said England had been an active participant who enjoyed enacting the scenes portrayed on camera.
"This was simply for the amusement of Private England and the other soldiers," he said.
In photographs published around the world in April 2004, England was shown holding a naked Iraqi prisoner by a leash, and pointing to a naked inmate's genitals.
England's original guilty plea was rejected at a military tribunal earlier this year.
The military judge then was not convinced that she knew that what she had been doing was wrong.
