The US has said the overnight suicide bombings in Saudi Arabia will not derail a fresh US push to forge an end to the conflict between Israel and the Palestinians.
The Saudi authorities have said the triple bombings in Riyadh killed at least 29 people - including nine bombers and seven Americans - and injured 194.
However, US State Department officials have warned the death toll could climb to 40 or 50.
Earlier, US Secretary of State Colin Powell visited one of the bombed housing compounds in Riyadh. Mr Powell vowed that those responsible would be hunted down.
Addressing an audience in Indianapolis, President Bush said the US would find those responsible and they would learn the meaning of American justice.
The Russian President, Vladimir Putin, said the Saudi Arabia bombings and the bombing in Chechnya over the weekend 'bore the same imprint'.
The Department of Foreign Affairs has said that at the moment there are no indications of any Irish casualties in the attacks. More than 2,000 Irish people work in the Gulf State.
