As the two leaders met, a journalist sitting in the third row jumped up, shouting:
"It is the farewell kiss, you dog,"and threw his shoes one after the other towards Bush.
The President, ducked and was not hit.
The journalist, Muntazer al-Zaidi from Al-Baghdadia channel which broadcasts from Cairo, was removed from the room by security staff.
Soles of shoes are considered the ultimate insult in Arab culture.
Other Iraqi journalists stood up to apologise.
"Thanks for apologising on behalf of the Iraqi people. It doesn't bother me. If you want the facts, it was a size 10 shoe that he threw".
Playing down the incident, the President later added:
"I don't know what the guy's cause is... I didn't feel the least bit threatened by it."
