Shibbir Ahmed, New York: The United States is marking the 25th anniversary of the September 11, 2001, terrorist attacks on Friday, with memorial ceremonies taking place across the country. In New York, victims’ relatives are gathering at the World Trade Center site to remember those who were killed in the attacks, while moments of silence mark key points in the timeline of that morning.

At the 9/11 Memorial in Lower Manhattan, family members are reading the names of their loved ones who died in the attacks. This year’s commemoration also includes a new moment of silence honoring people who were exposed to toxic dust and debris after the collapse of the World Trade Center and later died from related illnesses.

On September 11, 2001, al-Qaida terrorists hijacked four commercial airplanes. Two planes crashed into the World Trade Center towers in New York, one struck the Pentagon near Washington and the fourth crashed in a field near Shanksville, Pennsylvania, after passengers and crew members fought the hijackers. A total of 2,977 people were killed in the attacks.

The consequences of the attacks have continued long after that day. Thousands of firefighters, police officers, emergency workers, volunteers and others who worked at or around Ground Zero were exposed to toxic substances. More than 600 New York City firefighters have since died from illnesses related to their 9/11 exposure, according to figures cited by Reuters.

Memorial ceremonies are also being held at the Pentagon and at the Flight 93 National Memorial near Shanksville. President Donald Trump is attending the Pentagon observance, while Vice President JD Vance and all four living former presidents are attending the New York commemoration, according to Reuters and the Associated Press.

New York also held commemorative events ahead of Friday’s anniversary. On Wednesday night, a special drone installation titled “2,977 Lights Over New York Harbor” illuminated the sky above New York Harbor. The display featured 2,977 lights, representing each person killed in the 2001 attacks, before forming the outline of the Twin Towers at full architectural scale. Organizers said the project was developed in collaboration with 9/11 family members, survivors and first responders.

The city’s commemoration will continue Friday evening with the annual “Tribute in Light.” Two powerful beams of light will rise from Lower Manhattan, creating a symbolic representation of the Twin Towers and honoring those who died in the attacks. The 9/11 Memorial has scheduled the installation from Friday evening through early Saturday morning.

Twenty-five years later, the anniversary remains more than a remembrance of those who died on September 11, 2001. It also reflects the continuing grief of victims’ families, the sacrifices of first responders and the lasting health consequences faced by thousands of people who worked at Ground Zero.

For New York and the nation, the 25th anniversary is a moment to remember the lives lost, honor those who responded and preserve the history of a day that profoundly changed the United States.

Shibbir Ahmed, New York: Twenty-five years have passed since the devastating terrorist attacks of September 11, 2001. A quarter-century later, the loss of nearly 3,000 lives, the sacrifice of thousands of first responders, and the attacks’ lasting health and social consequences remain deeply embedded in the American memory. This year, New York, Washington and Pennsylvania will mark the 25th anniversary of 9/11 with a series of commemorations and public events.

Main Commemoration in New York

The main 9/11 commemoration will take place Friday at the 9/11 Memorial Plaza in Lower Manhattan, with family members of the victims participating in the ceremony. The program will begin at 8:40 a.m. and is primarily a private gathering for victims’ families, although the ceremony will be streamed live online.

Family members will read the names of those killed in the 2001 attacks as well as victims of the 1993 World Trade Center bombing. Moments of silence will mark several key moments of the attacks, including the aircraft impacts, the collapse of the Twin Towers, the attack on the Pentagon and the crash of Flight 93.

A special moment of silence will also honor those who died in the years following the attacks from 9/11-related illnesses. Vice President JD Vance and other administration officials are expected to attend the New York commemoration. President Donald Trump, meanwhile, will mark the 25th anniversary at the Pentagon instead of attending the New York ceremony.

First Moment of Silence at 8:46 a.m.

At 8:46 a.m. on September 11, 2001, the first hijacked aircraft, American Airlines Flight 11, struck the North Tower of the World Trade Center. The moment will be marked with the first moment of silence during the New York commemoration.

The ceremony will also remember the impact of the second aircraft on the South Tower, the collapse of both towers, the attack on the Pentagon and the crash of Flight 93 in Pennsylvania.

A total of 2,753 people were killed in New York, while 184 people died at the Pentagon in Arlington, Virginia. Another 40 passengers and crew members were killed when United Airlines Flight 93 crashed in Pennsylvania.

New Exhibition at the 9/11 Museum

For the 25th anniversary, the National September 11 Memorial & Museum in New York is launching a new exhibition titled “In Their Honor: 25 Years of 9/11-Inspired Service.”

Opening to the public on September 12, the exhibition will highlight stories of service, sacrifice and humanity over the 25 years since the attacks. It explores how individuals and communities transformed grief into public service and acts of compassion.

The museum is also introducing a new digital educational experience designed to help a new generation understand the history of 9/11 and its long-term impact. According to the museum, nearly 100 million Americans were either not yet born or were too young to remember the attacks. Connecting this generation with the history and legacy of 9/11 is one of the major goals of this year’s anniversary programs.

Trump to Mark Anniversary at Pentagon

In Arlington, Virginia, President Donald Trump is expected to attend and speak at the 25th anniversary commemoration at the Pentagon Memorial. The Pentagon was the third major target of the September 11 attacks. At 9:37 a.m., American Airlines Flight 77 struck the Pentagon. A total of 184 people were killed, including people inside the building as well as passengers and crew members aboard the aircraft. Vice President Vance will attend the main commemoration in New York.

Pennsylvania Also to Hold Commemorations

At the Flight 93 National Memorial in Pennsylvania, a commemorative ceremony will take place Friday from 8:30 a.m. to 10:30 a.m. The names of the 40 passengers and crew members aboard Flight 93 will be read, followed by the ringing of the Bells of Remembrance. A second ceremony will take place from 1 p.m. to 2:30 p.m., featuring additional commemorative activities and a public wreath-laying ceremony at the memorial.

New York’s Nighttime “Tribute in Light”

After a full day of remembrance, New York’s skyline will once again be illuminated by the historic Tribute in Light—two powerful beams of light representing the Twin Towers destroyed in the attacks. For the 25th anniversary, a special program titled “9/11 Tribute in Light: Live from Lower Manhattan” is scheduled to air nationally beginning at 8 p.m. on major television networks and other platforms.

The program will connect audiences across the country with the commemoration in New York and the annual Tribute in Light, bringing the day of remembrance to a national audience.

New Initiative in New York City

As part of this year’s 25th anniversary observance, New York City is officially recognizing September 11 as a Day of Remembrance and Service. The administration of Mayor Zohran Mamdani is emphasizing citywide remembrance, moments of silence, educational programs and volunteer service.

The city has also established a new Continuity and Mission Assurance Team, aimed at ensuring that essential city government operations and services can continue during emergencies while strengthening preparedness and coordination among city agencies.

25 Years Later, the Memory of 9/11 Endures

Twenty-five years later, 9/11 remains far more than a historical event. It continues to shape the security, politics, foreign policy and public health of New York, Washington and the United States as a whole.

This year’s commemorations are therefore not limited to honoring those who were killed. They also recognize first responders, rescue workers, survivors, families who lost loved ones and a new generation born after the attacks. A quarter-century later, the message remains the same: Never Forget.
