Communities across the United States are marking the 25th anniversary of the September 11, 2001, terrorist attacks with solemn remembrances, stair climbs, and flag displays, according to reports from RTE and bostonglobe.com. On that day twenty-five years ago, 19 al-Qaeda operatives hijacked four commercial airplanes, leading to the deaths of 2,977 people in New York, at the Pentagon, and in a Pennsylvania field.
Nation Marks Quarter-Century Since Sept. 11 Terror Attacks
President Donald Trump is observing Friday’s anniversary by attending a commemorative ceremony at the Pentagon, marking his second year recognizing the date at that location. Vice President JD Vance, along with former presidents George W. Bush, Barack Obama, Bill Clinton, and Joe Biden, are expected to attend the primary Ground Zero observance in lower Manhattan. Additional administration officials are scheduled to participate in a remembrance ceremony in Shanksville, Pennsylvania.
Lower Manhattan Ceremony and Security Preparations
The memorial service at Ground Zero features no formal speeches; instead, bereaved family members will read the names of the victims, accompanied by the ringing of a bell during major moments of the attacks. Huge crowds are expected to gather in lower Manhattan for the service.
To secure the site, the Secret Service has established a ring of steel around the 9/11 Memorial and Museum. Police Commissioner Jessica Tisch stated that an anti-drone team has been deployed as a precaution, though authorities have emphasized there is no intelligence indicating a specific threat against the gathering. Ahead of the official anniversary, a drone display lit up the skies over New York Harbor with 2,977 lights—one for every individual killed.
Local Mayoral Attendance Draws Debate Amid Health Disclosures
New York City’s commemoration also involves the attendance of Democratic Mayor Zohran Mamdani, the city’s first Muslim mayor, which has drawn opposition from right-wing groups and former mayor Rudy Giuliani. A petition urging Mamdani to stay away has gathered more than 100,000 signatures. City Council member Shahana Hanif defended the mayor, stating to CNN that it is concerning he is treated differently because he is Muslim.

Mamdani recently received praise for releasing thousands of municipal documents detailing what city officials historically knew regarding air toxicity levels in lower Manhattan following the tower collapses. Months of lingering dust and pollution caused cancers from which thousands of New Yorkers still suffer. According to the federal healthcare program established for those affected, more than 9,400 people have died from 9/11-related illnesses beyond those killed directly on the day of the attacks.
