NEW YORK (AP) — Relatives and loved ones of 9/11 victims will convene Sunday to mark the 15th anniversary of the terror attacks.

Organizers have planned some additional music and readings to mark the milestone anniversary at ground zero.

But they are keeping traditions that have made the ceremony a constant in how America remembers Sept. 11, even as ground zero and the nation changes.

The customs include moments of silence and tolling bells, an apolitical atmosphere and the reading of the nearly 3,000 names of those killed in New York, at the Pentagon and near Shanksville, Pennsylvania.

President Barack Obama will speak at an observance at the Pentagon. Hundreds of people also are expected at a ceremony at the Flight 93 National Memorial in Shanksville.
