President Bush has condemned the bombing of a Shi'ite mosque in Iraq, calling it a political act intended to cause strife in the nation.
At a cabinet meeting Thursday, Mr. Bush said the United States will continue to work with what he called the "voices of reason" to help Iraq continue to work toward a democracy that unites.
He also said the United States is serious in its commitment to help rebuild the Askariya shrine.
Insurgents are believed to be responsible for the attack.
But in a speech broadcast on Thursday on Iranian state television, Iran's President Mahmoud Ahmadinejad blamed western nations for the destruction. Mr. Ahmadinejad also warned that countries such as Israel and the U.S. would be targets for Muslim anger.
Iran is a majority Shi'ite Muslim nation.
Sunni and Shi'ite leaders in Iraq have appealed for calm.
But radical Shi'ite cleric Moqtada al-Sadr accused the United States and the Iraqi government of failing to protect the 12-hundred year old shrine. Street protests in Iraq against the attack continued Thursday.
