Americans are marking 24 years since the Sept. 11, 2001, attacks with solemn ceremonies, volunteer work, and other tributes honouring the victims.
Many loved ones of the nearly 3,000 people killed will join dignitaries and politicians at commemorations Thursday in New York, at the Pentagon, and in Shanksville, Pennsylvania.
Others choose to mark the day at more intimate gatherings.

The remembrances are being held during a time of increased political tensions. The 9/11 anniversary, often promoted as a day of national unity, comes a day after conservative activist Charlie Kirk was shot and killed while speaking at a college in Utah.
Kirk’s killing is expected to prompt additional security measures around the 9/11 anniversary ceremony at the World Trade Centre site in New York.

At ground zero in lower Manhattan, the names of the attack victims will be read aloud by family and loved ones in a ceremony attended by Vice President JD Vance and his wife, second lady Usha Vance Moments of silence will mark the exact times when hijacked planes struck the World Trade Centre’s iconic twin towers, as well as when the skyscrapers fell
At he Pentagon in Virginia, the 184 service members and civilians killed when hijackers steered a jetliner into the headquarters of the U.S. military will be honoured.
President Donald Trump and first lady Melania Trump will attend the service before heading to the Bronx for a baseball game between the New York Yankees and Detroit Tigers Thursday evening.
