The White House appeared firm on Monday in accusing Iran of allegedly arming the insurgents in Iraq but denied this is a prelude to attack Iran.

White House spokesman Tony Snow, when asked whether the United States is confident in the accusations, said: "Yes."

When asked whether the United States was confident that the weaponry was coming into Iraq with Teheran's approval, Snow said: "Yes."

Snow stressed that the allegations made by U.S. military officials in Baghdad on Sunday that Iran is supplying potent munitions to Iraqi insurgents is not a shift in rhetoric, and the United States is not aiming to go to war with Iran.

According to a report by the Washington Post on Monday, senior U.S. military officials in Iraq presented on Sunday mortar shells, rocket propelled grenades and a powerful cylindrical bomb, capable of blasting through an armored Humvee. They alleged that these were manufactured in Iran and supplied to Shiite militia in Iraq for attacks on U.S. and Iraqi troops.

The United States has repeatedly accused Iran of providing support to Iraq's insurgents. Iran has denied the charges.
