British Prime Minister Tony Blair says images of British troops apparently abusing an Iraqi prisoner are "totally unacceptable."

Mr. Blair told British television stations Saturday, that if the abuse is confirmed it should be "condemned utterly." However he said he believes most British troops in Iraq are doing a good job to help Iraqis.

Britain's military launched an investigation after the Daily Mirror newspaper published photographs showing British soldiers apparently beating and urinating on an Iraqi captive.

The pictures surfaced only days after images were aired on U.S. television showing American troops humiliating Iraqi prisoners.

President Bush expressed what he called a "deep disgust" about the pictures. He told reporters at the White House Friday that such behavior "does not reflect the nature of the American people."

The U.S. military has filed criminal charges against six soldiers in the case and more soldiers are expected to be charged.

In some of the pictures, American soldiers are shown laughing, as naked male prisoners are stacked in a pyramid or positioned to simulate sexual acts.

The photographs have sparked outrage around the world. The Arab League called on those responsible to be brought to justice for what it termed the "savage acts."
