The nation paused Friday for rituals of somber reflection to mark the anniversary of the Sept. 11 terror attacks.
At ground zero in Lower Manhattan, families of the lost gathered for a touchstone of the annual remembrance — the reading of the names of the almost 3,000 people killed there 14 years ago.
For the first time, the ceremony took place in the shadow of full rebirth: One World Trade Center, the 1,776-foot tower that rose where two fell, opened for business less than a year ago.
The public memorial at the site will be reserved for the families during the morning but will be open to everyone later in the day. An estimated 20,000 people gathered there on the night of Sept. 11 last year.
At the White House, President Barack Obama walked onto the South Lawn and bowed his head for a moment of silence. He was to travel to Fort Meade, Maryland, to recognize the work of the military. Defense Secretary Ashton Carter led a commemoration at the Pentagon.
At the national memorial site in Shanksville, Pennsylvania, where United Airlines Flight 93 crashed, the visitor center opened Thursday.
Ceremonies were planned in places all over the country. A sculpture was to be dedicated in Doylestown, Pennsylvania. The Statehouse in Ohio planned to display almost 3,000 flags. A Chicago high school planned to serve breakfast to police and firefighters.
