WASHINGTON (AFP) - US President George W. Bush and his top officials ran roughshod over the truth in the run-up to the Iraq war lying a total of 935 times, a study released Wednesday found.

Bush and his then secretary of state Colin Powell made the most false statements as they sought to drum up support for the March 2003 invasion to topple Iraqi dictator Saddam Hussein, the study alleged.

In a damning report, the Center for Public Integrity found "935 false statements by eight top administration officials that mentioned Iraq's possession of weapons of mass destruction, or links to Al-Qaeda, on at least 532 separate occasions."
