Iraq has vowed to step up suicide attacks to defeat the US-led invasion. One of Iraq?s top leaders says that 4,000 people from Arab countries have arrived in Iraq, ready to give their lives as suicide bombers. He predicts widespread attacks against American and British troops, and all who support them, both inside Iraq and elsewhere in the Arab world.

Iraqi Vice President Taha Yassin Ramadan said suicide attacks and any method that stops coalition forces would be used. He said Saturday?s suicide attack by a soldier dressed as a taxi driver near Najaf was just the beginning. Iraqi TV said Saddam Hussein posthumously promoted the soldier and has awarded his family a large sum of money.

Maj. Gen. Stanley McChrystal?s reaction.

?We?re very concerned about it. It looks and feels like terrorism.?

In his weekly radio address Saturday, President Bush condemned what he called Iraqi war crimes.

?In the last week, the world has seen firsthand the cruel nature of a dying regime. In areas still under its control, the regime continues its rule by terror. Prisoners of war have been brutalized and executed. Iraqis who refuse to fight for the regime are being murdered. An Iraqi woman was hanged for waving at coalition troops.?

But how will coalition forces deal with these tactics?

?It doesn?t affect the operation at large, but to protect our soldiers, it clearly requires great care.?

The Pentagon says that although the troops will be more cautious, the specific rules of engagement that they operate under won?t change.
