9/11 anniversary to be marked with tributes - Sep 11th, 2013 - National
— Sept. 11 victims' loved ones will gather at ground zero to commemorate the attacks' anniversary with the reading of names, moments of silence and serene music that have become tradition.
At Wednesday's ceremony on the 9/11 memorial plaza, relatives will recite the names of the nearly 3,000 people who died when hijacked jets crashed into the World Trade Center, at the Pentagon and near Shanksville, Pa.
The Pentagon and the Flight 93 National Memorial in Shanksville also plan name-reading, wreath-laying and other tributes.
The anniversary is expected to be the last before the Sept. 11 museum opens at ground zero. That's due this spring.
Changes also are coming at the Flight 93 National Memorial in Shanksville. Officials gathered there Tuesday to mark the start of construction on a visitor center.
President Barack Obama will observe the 12th anniversary of the terrorist attacks on the World Trade Center and the Pentagon with a moment of silence and a visit to the Pentagon Memorial.
In the afternoon, Obama will take part in a service project to commemorate the National Day of Service and Remembrance.
