The US President, George W Bush, is not landing at Shannon Airport this evening as was expected.
Air Force One was to make a brief refuelling stop shortly before 5pm. However, Mr Bush is flying directly from the former Soviet republic of Georgia to Washington.
Mr Bush was on a five-day trip through Europe where he marked the 60th anniversary of the end of World War II.
A small protest had been planned for Shannon by anti-war protestors. A massive security operation in the area involving airport police and the gardaí has been stood down.
Bush praises Georgia reforms
Speaking before a large crowd in the Georgian capital, Tbilisi, this morning, Mr Bush praised the country's democratic reforms and said Georgia's territorial integrity had to be respected by all nations.
His comments were an apparent reference to American support to Georgia's efforts to reassert sovereignty over two pro-Russian regions that have declared their autonomy.
The president was the first US leader to visit the country. He described the so-called Rose Revolution, which led to the peaceful replacement of the previous government in 2003, as a powerful moment in history.
Mr Bush made his speech in Tbilisi's Freedom Square, which became the rallying point for the revolution two years ago.
He also met Georgia's President, Mikhail Saakashvili, who leads Georgia's reformist, western-looking government.
