"After giving his speech Mr Bush fielded questions from reporters, many of which asked him about the current inquiry into the 11 September attacks on Washington and New York.
He reiterated his claim that his administration could have done nothing more to prevent the attacks, saying: "Had I had any inkling that people would be flying aeroplanes into buildings, I would have moved heaven and earth to save the country."
Mr Bush also said that the lesson of those attacks had been that America had to deal with "gathering threats" before they came to fruition, a policy that catalysed the US-led invasion of Iraq.
Mr Bush initially justified the invasion, which has so far claimed the lives of more than 670 US troops, as being necessary to rid Iraq of banned weapons of mass destruction. However, since Iraq fell to coalition hands no such weapons have been found."
