LOWER MANHATTAN -- Holding photos and reading names of loved ones lost 16 years ago, 9/11 victims' relatives marked the anniversary of the attacks at ground zero on Monday with a solemn and personal ceremony.
Every Sept. 11 since the date of the deadliest terror attack on American soil, Rob Fazio has come to the place where his father, Ronald Carl Fazio, and thousands of others died.
"I'll come every year for the rest of my life," the son said. "It's where I get my strength."
At least 1,000 family members, survivors, rescuers and officials were gathered as the ceremony at the World Trade Center began with a moment of silence and tolling bells. Then, relatives began reading out the names of the nearly 3,000 people killed when terrorist-piloted planes hit the trade center, the Pentagon and a Pennsylvania field, hurling America into a new consciousness of the threat of global terrorism.
9/11 Anniversary Complete Coverage
Some said they couldn't believe 16 years had passed since a tragedy that still seemed so present on the anniversary. To others, it was an occasion to plead for a return to the sense of unity they felt after the attacks.
"Our country came together that day. And it did not matter what color you were, or where you were from," said a tearful Magaly Lemagne, who lost her brother, Port Authority of New York and New Jersey Police Officer David Prudencio Lemagne. She implored people to "stop for a moment and remember all the people who gave their lives that day.
"Maybe then we can put away our disagreements and become one country again."
Nicholas Haros Jr. saw a glimpse of that cohesiveness in the country's response to catastrophic recent hurricanes Irma and Harvey. Irma was making its way through the Southeast as a tropical storm while 9/11 anniversary ceremonies unfolded in New York, the Pentagon and near Shanksville, Pennsylvania.
"God bless, and be New York strong," Maureen Tipping-Lipshie urged those affected by Irma after she remembered her brother, John James Tipping II.
Sixteen years later, the quiet rhythms of commemoration have become customs: a recitation of all the names of the dead, moments of silence and tolling bells, and two powerful light beams that shine through the night.
Yet each ceremony also takes on personal touches. Some name-readers added messages ranging from the universal to the personal - updates on family graduations and marriages, memories of personality traits and favorite foods.
Some have never even had a chance to meet the relatives they lost on Sept. 11, 2001.
"I wish more than anything that I could have met you," Ruth Daly said, her voice breaking, after she read names in remembrance of her slain grandmother, Ruth Sheila Lapin. "I'm very proud to be your namesake. I hope you're watching down on me from heaven."
Meanwhile, President Donald Trump, a native New Yorker observing the anniversary for the first time as the nation's leader, observed a moment of silence at the White House with first lady Melania Trump.
The Trumps also planned to participate in a 9/11 observance at the Pentagon. Defense Secretary Jim Mattis and Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, are hosting a private observance for victims' relatives there at 9:11 a.m. Monday. After the names are read at that ceremony, there's a public observance, with a wreath-laying and remarks.
Vice President Mike Pence and U.S. Secretary of the Interior Ryan Zinke are scheduled to deliver remarks at the Flight 93 National Memorial near Shanksville. It's on the rural field where one of the airliners crashed after passengers and crew fought to wrest control away from the terrorists who'd hijacked it and were heading for Washington.
Construction continues at the Shanksville memorial, where ground was broken Sunday for a 93-foot (28 meters) tall Tower of Voices to honor the 33 passengers and seven crew members who died.
Rebuilding and reimagining also continues at ground zero, where the third of four planned office towers is set to open next year. Work toward a $250 million performing arts center continues after a design was unveiled last fall. Most recently, plans were announced this spring to transform a grassy clearing on the memorial plaza into a walkway and area dedicated to 9/11 rescue and recovery workers.
The ceremony on the National Sept. 11 Memorial plaza strives to be apolitical: Politicians can attend, but since 2011, they haven't been allowed to read names or deliver remarks.
Yet last year's 15th-anniversary ceremony became entangled in the narrative of a fractious presidential campaign when Democratic nominee Hillary Clinton left abruptly, stumbled into a van and ultimately revealed she'd been diagnosed days earlier with pneumonia.
This year, the focus remained on the names read out beneath the waterfall pools and lines of trees.
"It does feel good to know you have other people who are feeling the same pain that you're in," Marvaline Monroe said as she headed into the ceremony to remember her brother, Keith Broomfield. She comes to the ceremony as often as she can.
"It's very hard. We'll never forget, but we just have to live with the memories that we have of him."
Delaney Colaio read names in honor of the three relatives she lost: her father, Mark Joseph Colaio, and her uncles Stephen J. Colaio and Thomas Pedicini. She is making a documentary about the children who lost parents in the attacks.
"I stand here as a reminder to the other families of 9/11 and to the world," she said, "that no matter how dark moments life can get, there is light ahead if you just choose hope."
