The National September 11 Memorial & Museum's annual Ground Zero ceremony centres on relatives reading aloud the names of people killed on 9/11 and in the 1993 World Trade Center bombing

Marking twenty-five years since the attacks that killed 2,977 people, the ceremony has become contested. A petition led by a victim's widower asks organizers to bar Mayor Zohran Mamdani, who intends to attend and has designated the date a citywide day of remembrance and service.
