"We express our total condemnation and disgust at any abuses that have been carried out," he said, while his government said some soldiers implicated in the mistreatment could soon face prosecution.
A new opinion poll showed support for Blair's Labor Party has fallen to its lowest level for 17 years following the reports of abuse of Iraqi prisoners.
A February 4 Red Cross report that appeared on the Wall Street Journal website on Monday said delegates of the international relief agency saw US troops keeping Iraqi prisoners naked for days in darkness at the Abu Ghraib jail in October, and were told by the intelligence officer in charge it was "part of the process."
The report also described British troops forcing Iraqi detainees to kneel and stomping on their necks in an incident in which one prisoner died.
The International Committee of the Red Cross said it had repeatedly alerted US-led occupation authorities to practices it described as "serious violations of international humanitarian law" and "in some cases tantamount to torture."
PRESSURE BUILDS
The Red Cross visit took place two months before pictures were taken of US troops abusing prisoners, which later led to criminal charges against seven soldiers.
Pictures of Iraqi prisoners being humiliated by Americans at Abu Ghraib prison near Baghdad were broadcast by CBS television two weeks ago, triggering the scandal.
US officials have described the abuse as isolated. Bush on Saturday called the acts the "wrongdoing of a few."
Bush told reporters after his meeting with Rumsfeld he continued to stand firmly behind Rumsfeld despite calls by some Democrats for the secretary to resign. Rumsfeld said last week he would not quit "simply because people try to make a political issue out of it."
"You're doing a superb job. You're a strong secretary of defence and our nation owes you a debt of gratitude," Bush told Rumsfeld.
But pressure on top officials showed no signs of abating.
The independent Army Times newspaper, widely read in the US military, rebuked Rumsfeld and Gen. Richard Myers, chairman of the Joint Chiefs of Staff, on Monday for "a failure of leadership," and added that accountability might mean "relieving top leaders from duty in a time of war."
A member of U.S.-backed Iraqi Governing Council said senior US officials should be held accountable for the abuse of Iraqi prisoners, while the US ambassador to NATO said the scandal had plunged the Bush administration into crisis.
The US Senate on Monday unanimously passed a resolution condemning the mistreatment of Iraqi prisoners, as Congress awaited arrival of new images of abuses of detainees at the prison.
Pentagon spokesman Lawrence Di Rita told reporters that officials hadn't ruled in or out release of the unpublished photos seen by Bush.
Di Rita said the pictures included "inappropriate behaviour of a sexual nature," but provided no details. He also did not specify the content of the pictures Bush viewed.
White House spokesman Scott McClellan said Bush had seen more than a dozen photographs and his reaction "was one of deep disgust and disbelief that anyone who wears our uniform would engage in such shameful and appalling acts. It does not represent our United States military and it does not represent the United States of America."
