George W Bush has thanked the American public for re-electing him as the country's president.
He scored a close victory over his challenger John Kerry, with the state of Ohio deciding the contest.
"America has spoken and I am humbled by the trust and confidence of my fellow citizens," Mr Bush said.
Earlier, Mr Kerry had admitted defeat, saying he knew he would not be the winner once the votes were counted. Mr Bush will serve for another four years.
