This Friday marks the 25th anniversary of the September 11 attacks. The National September 11 Memorial & Museum will commemorate the 2,977 lives lost in the tragedy with its annual ceremony.
The somber event will be held at the site where the Twin Towers once stood.
Here is what you need to know about the annual remembrance ceremony:

The ceremony will adhere to its traditional format, with the addition of a new moment of silence for those who have died from 9/11-related illnesses or injuries.
The first of seven moments of silence will be observed at 8:46 a.m., followed by church bells ringing across the city.
Families of the victims from the 2001 and 1993 attacks will read names in pairs, pausing for these moments of silence:

The ceremony will conclude with the Playing of Taps at 1 p.m.
Who will be there
Mayor Zohran Mamdani has committed to attending the solemn event for the first time as mayor, despite criticism from some victims’ families and first responders over his remarks on Israel.
Despite the backlash, he plans to stand in solidarity with the families, survivors, and first responders affected by the attacks.
