WASHINGTON � Some parts of the war on terrorism have been fought outside Afghanistan, and in the shadows.

Bush administration officials say more than 2,400 people have been detained and interrogated worldwide in the effort. The U.S. military is holding and questioning about 600 Taliban or al-Qaida suspects at the Navy base in Guantanamo Bay, Cuba.

Questioning of those prisoners has led to arrests in Algeria, Indonesia, Jordan, Pakistan, Kenya, France, Singapore, Somalia and Britain, officials said. They said information from prisoners has helped authorities foil terrorist attacks in Afghanistan, Pakistan, France, Turkey, Yemen and Saudi Arabia.

So far, only Zacarias Moussaoui has been charged directly in the Sept. 11 attacks. The Frenchman's trial is scheduled for January.

On the financial front, authorities worldwide have frozen more than $112 million in alleged terrorist assets. U.S. officials have seized more than $6.8 million domestically and more than $16 million in outbound currency.

The U.S. military is training forces in Yemen and the former Soviet republic of Georgia to fight terrorists, and helped the Philippines fight an al-Qaida-linked group earlier this year.

Filipino forces killed several leaders of the Abu Sayyaf group and freed an American hostage, although a second American and a Filipino hostage were killed in the rescue.
