Meanwhile, the Bush administration continues its campaign against Iran. On Tuesday, President Bush threatened to confront Iran for what he said was its backing of attacks on U.S. troops in Iraq.

President Bush: “They cannot escape responsibility for aiding attacks against coalition forces and the murder of innocent Iraqis. The Iranian regime must halt these actions. And until it does, I will take actions necessary to protect our troops. I have authorized our military commanders in Iraq to confront Tehran’s murderous activities.”

Bush’s comments came as U.S. troops arrested seven Iranian nationals in Baghdad. They were released hours later.
