Maria Tsvetkova, Idrees Ali and Joseph AxSeptember 11, 2026 — 11:25pmTwenty-five years after the deadliest attack on US soil, Americans paused on Friday to commemorate the nearly 3000 people killed when hijacked planes slammed into the World Trade Centre, the Pentagon and a field in Pennsylvania – and to wrestle with the consequences of September 11 that reverberate to this day.In New York, family members of the victims joined Vice President JD Vance and four former US presidents at Ground Zero in Lower Manhattan. The ceremony began, as always, at 8.46am with a moment of silence to remember the shocking instant when American Airlines Flight 11 struck the World Trade Centre’s North Tower.New York City Fire Department (FDNY) members visit the memorial ahead of the ceremony.BloombergThe site of the World Trade Centre attacks on Friday, now the National 9/11 Memorial and Museum.BloombergShortly after, victims’ family members began reading aloud the names of all 2977 people who died on September 11, as well as the six people killed in the 1993 World Trade Centre bombing, a sombre recitation that will last for hours. In a reminder of the time that has passed, some readers were children who had never met the relatives they lost in 2001.Other moments of silence, marking when the other three airplanes crashed and the two towers collapsed, will follow. For the first time, a seventh silence will be observed to honour the thousands who have died since 2001 from illnesses tied to the toxic dust that poisoned the air for months afterward.A woman and child pause at the memorial on Friday morning.Spencer Platt/Pool Getty Images North America via APPeople walk in the Oculus near the memorial on the 25th anniversary of the attacks.AP Photo/Angelina KatsanisGregory Carafello came to the ceremony to honour the memory of his lifelong friend James Martello, who worked at Cantor Fitzgerald, the financial firm that lost more than 650 employees in the attacks. Carafello himself was on the 18th floor of the South Tower but managed to evacuate.“Everyone should realise that it was a very bad, catastrophic day for many families,” he said. “These were not warriors. These were people like you and me going to work.”US Vice President JD Vance speaks with former New York City mayor Michael Bloomberg as former President George W.

She brought him her father’s grave last week and was attending a memorial ceremony in Boston on Friday.“This year, there’s this new sadness in knowing that they won’t ever get to know each other,” Ogonowski, who has worked in disaster relief and humanitarian assistance, said in a phone interview. “My father will never know his grandson. And my son will never know his grandfather.“We owe it to my father and all the others that we lost on that day to make sure that we continue to teach future generations about what happened, about who these people were, who these heroes were, how our country came together and became stronger because of it,” she added.A generation of Americans has grown up since 2001 who are too young to remember the attacks but whose lives were fundamentally altered by them.The attacks initiated the “war on terror,” which led to the creation of the Department of Homeland Security and the US invasions of Afghanistan and Iraq that lasted years. The resulting public backlash helped fuel Trump’s rise a decade ago, when he vowed not to start new foreign entanglements – a promise being tested by the current Iran war.At home, Americans expressed deep solidarity and patriotism, as well as sorrow, in the immediate wake of the attacks.At the same time, however, Muslim Americans and immigrants from Muslim-majority countries faced a rise in prejudice and hate crimes. Public polls have found 9/11 colours Americans’ perceptions of Muslims to this day. New York Mayor Zohran Mamdani, the city’s first Muslim mayor, has faced calls from some Republicans to skip Friday’s ceremony, which he rejected.Zohran Mamdani, mayor of New York, arrives ahead of the 25th anniversary commemoration ceremony at the National 9/11 Memorial and Museum.BloombergRudy Giuliani, former mayor of New York, arrives ahead of the 25th anniversary commemoration ceremony.BloombergCasualties were not limited to those who perished on September 11. Many rescue workers who spent weeks or months at the site afterward, as well as nearby residents and others, were sickened by toxins in the air and eventually died.Patrick Whalen’s father, also named Patrick, was a New York City firefighter who responded to the attacks and continued working at Ground Zero for months amid the dust and rubble. In 2020, he was diagnosed with cholangiocarcinoma, a rare cancer linked to exposure to toxic carcinogens, and died in 2021.“The government told him it was safe to breathe, and, obviously, it was not true,” the younger Whalen said after a New York City Fire Department memorial service this week.A woman mourns at the September 11 memorial plaza in Lower Manhattan.Dave Sanders/Pool The New York Times via APInformation that the air at Ground Zero was safe to breathe came from the US Environmental Protection Agency. Its former administrator, Christine Todd Whitman, apologised in a 2016 interview with The Guardian, saying the agency did its best with the knowledge it had.The New York City Fire Department lost 343 members on September 11. More than 600 additional firefighters, including some retired members who took part in the rescue effort, have died of 9/11-related illnesses since then, department figures show. Twenty-six have died this year alone.ReutersMore:September 11 attacksUSAExtremismNew YorkReliving historyDonald TrumpZohran MamdaniFrom our partners
