;WASHINGTON (AP) - The White House and the CIA on Tuesday adamantly denied a report that the Bush administration concocted a fake letter purporting to show a link between Saddam Hussein's regime and al-Qaida as a justification for the Iraq war.

The allegation was raised by Washington-based journalist Ron Suskind in a new book, "The Way of the World," published Tuesday. The letter supposedly was written by Tahir Jalil Habbush al-Tikriti, director of Iraqi intelligence under Saddam Hussein.

"The White House had concocted a fake letter from Habbush to Saddam, backdated to July 1, 2001," Suskind wrote. "It said that 9/11 ringleader Mohammad Atta had actually trained for his mission in Iraq thus showing, finally, that there was an operational link between Saddam and al-Qaida, something the vice president's office had been pressing CIA to prove since 9/11 as a justification to invade Iraq. There is no link."

Suskind said the letter's existence had been reported before, and that it had been treated as if it were genuine.

Denying the report, White House deputy press secretary Tony Fratto said, "The notion that the White House directed anyone to forge a letter from Habbush to Saddam Hussein is absurd."
