Bush administration officials say Saudi Arabia is cooperating fully in the search for militants who kidnapped an American and killed two others.
President Bush's National Security Advisor Condoleezza Rice says the government in Riyadh knows it faces a strong terrorist threat, and is working closely with the United States.
Secretary of State Colin Powell says the Washington is doing all it can to help Saudis restore a sense of security so attacks do not disrupt oil production and other commerce. Mr. Powell said Sunday that Saudi Arabia has done a great deal to fight terrorism, but could do more.
An Internet statement attributed to the al-Qaida terror network has claimed responsibility for killing one American and capturing another Saturday in Riyadh.
