An American woman soldier has pleaded guilty to charges of abusing prisoners at Abu Ghraib jail in Iraq, at a court martial in Texas.

Lawyers say Private Lynndie England agreed to a plea deal that will reduce her maximum jail sentence to 11 years.

Images of Pte England smiling and pointing at naked Iraqis sickened America and the rest of the world.

She is one of nine soldiers who were charged with mistreating Iraqi captives at Abu Ghraib in late 2003.

Some have pleaded guilty and have been sentenced to jail.

The defence has always contended that Pte England and other soldiers were acting on orders of army intelligence officials, who wanted to soften up prisoners before they were interrogated.

It is alleged that it was a policy which was sanctioned at the highest level.

But four top army officers were cleared last week of any wrongdoing at Abu Ghraib.

Only one senior soldier, Brig Gen Janis Karpinski, has been relieved of her command as a result of the scandal.
