U.N. Bombed in Baghdad

A suicide attacker's bomb exploded at United Nations' headquarters in Baghdad today, leaving 17 dead and dozens wounded. The attack is a further blow to security in U.S.-occupied Iraq, and further complicates the U.N.'s role there. After playing second fiddle to British and American aims in Iraq, can the U.N. avoid stepping into the line of fire?
