NEW YORK (AP) -- Thousands are expected at ceremonies in New York, the Pentagon and Shanksville, Pa. to mark eight years since the Sept. 11 terror attacks that killed nearly 3,000 people.
At a park near ground zero, family members will join with volunteers who helped at the site of the fallen trade center towers to read victims' names. Moments of silence will mark the times when the jetliners crashed into the towers and when each tower collapsed. Vice President Joe Biden plans to attend the ceremony.
In Washington, President Barack Obama and Defense Secretary Robert Gates will attend a wreath laying ceremony at the Pentagon memorial.
And in the Pennsylvania field where United Flight 93 crashed, former Secretary of State Colin Powell will deliver a speech.
Across the rest of the nation, many are finding ways to help their communities. The anniversary has been declared a national day of service.
