Dublin - Irish Prime Minister Brian Cowen on Wednesday congratulated Senator Barack Obama on being elected president of the United States, saying Obama's election was "a day of hope for the world".

"Barack Obama's remarkable personal story - allied to his eloquence and his huge political talents - sends a powerful message of hope to America's friends across the world."

"There is a palpable sense of history with the election of the first African-American president.

"On this day, we are all reminded of those who struggled for civil rights in America for so many years, as well as all of those who work for justice and peace around the world today."

Irish President Mary McAleese said Obama's win was "a beacon of hope" for the world.

"The election of Senator Obama was transformational in its power and scope, and serves as a beacon of hope, not just in America, but around the world, particularly in these turbulent times of anxiety and uncertainty.

"I hope he will be successful in charting a new and dynamic course for America in what will inevitably be a challenging and crucially important period in office."

Cowen also praised the defeated Republican candidate, who has Scots-Irish heritage, saying "for his immense contribution to American life, great credit is due to Senator John McCain, another long-standing and true friend of Ireland." (dpa)
