World leaders hastened to condemn the attacks, including Palestinian leader Yasir Arafat and Libya's Muammar el-Qaddafi.
European leaders began quiet discussions last night about how they might assist the United States in striking back, and Russia's president, Vladimir Putin, joined in expressing support for a retaliatory strike.
But in the West Bank city of Nablus, rejoicing Palestinians, who have been locked in a bitter struggle with Israel for almost a year, went into the streets to chant, "God is great!" and to distribute candies to celebrate the attacks.
Many governments took their own precautions against attack. Israel evacuated many of its embassies abroad, and non-essential staffers at NATO headquarters in Brussels were ordered home.
