A right-wing American television presenter who outspokenly supported the Iraq war has backtracked on his views.
No weapons of mass destruction have been found
The Fox News network's Bill O'Reilly told viewers he was now sceptical about the US president's claim that Iraq had weapons of mass destruction.
"I was wrong," said Mr O'Reilly, adding "all Americans should be concerned" that no such weapons had been found.
President George W Bush led the US to war in Iraq, claiming its arsenal of illegal weapons posed a threat.
However, since the war, successive teams of investigators have been unable to find any evidence that Iraq possessed these weapons of mass destruction.
David Kay, the US official appointed by President Bush to lead the search for Iraq's weapons, resigned last month, complaining that the intelligence that led to the war was mistaken.
Under growing pressure from his critics, President Bush has announced an inquiry into apparent pre-war intelligence failures.
Mr O'Reilly did not criticise the president, but instead indicated the blame lay with American's Central Intelligence Agency (CIA).
"I think every American should be very concerned for themselves that our intelligence is not as good as it should be," he said. "I don't know why [CIA director] Tenet still has his job."
Mr O'Reilly made his statement on ABC television, the US rival to Fox News, keeping a promise he made before the war to publicly apologise if no banned weapons were found in Iraq.
