US Secretary of State Hillary Clinton will attend a ceremony in Germany marking the 20th anniversary of the fall of the Berlin Wall, a German government official said on Friday.
She will join a host of world leaders for celebrations in Berlin on November 9, dubbed the "freedom party", which will take place at the capital's Brandenburg Gate.
Festivities will open with orchestral music, followed by thousands of gigantic dominoes being knocked down in the centre of the capital to symbolise the fall of the wall.
US President Barack Obama has already said he will not attend the celebrations as he will be in Asia.
British Prime Minister Gordon Brown, Russian President Dmitry Medvedev and French President Nicolas Sarkozy are among those expected in Berlin for the ceremony.
