President Bush has promised victory in the war on terror as he marks the third anniversary of the September 11 terrorist attacks.
Delivering his weekly radio address live Saturday, Mr. Bush said the United States will pursue terrorists wherever they sleep, train, or try to put down roots. Earlier, the president led a moment of silence on the White House lawn.
Meanwhile, in New York City, family members are reading out the names of the 2,749 people who died in the attacks that destroyed the World Trade Center.
A ceremony at Arlington National Cemetery outside Washington honored those killed in the attack on the Pentagon. Defense Secretary Donald Rumsfeld described Americans as being "resilient despite great loss."
And a ceremony in Shanksville, Pennsylvania remembered those aboard United Airlines Flight 93, which crashed in a nearby field as it flew toward the nation's capital.
