Live Updates: 25 years after Sept. 11 attacks, America reflects and remembers

Twenty-five years after Sept. 11, 2001, the casualties are still mounting. Roughly 6,000 first responders, survivors and volunteers have died from illnesses related to the attacks. The New York City Fire Department recently added the names of 36 firefighters who died from related diseases to its memorial wall.

"Thirty-six more reminders that the legacy of September 11th doesn't end on one single day," said FDNY Commissioner Lillian Bonsignore.

The September 11th Victim Compensation Fund has received at least 112,000 claims, awarding more than $18 billion.

New York City Mayor Zohran Mamdani recently documents from the aftermath of 9/11, which show that the city was aware of airborne toxins that later sickened and killed thousands.

"The government told us the air was safe to breathe," said Peter Raho, who worked as an accountant near Ground Zero and was later diagnosed with Non-Hodgkin's lymphoma.

The reading of the names of the deceased at Ground Zero will be punctuated by seven moments of silence:

• 8:46 a.m. ET: Hijackers deliberately crashed American Airlines Flight 11 into the North Tower of the World Trade Center
• 9:03 a.m. ET: Hijackers crashed United Airlines Flight 175 into the South Tower
• 9:37 a.m. ET: Hijackers crashed American Airlines Flight 77 into the Pentagon
• 9:59 a.m. ET: South Tower collapses
• 10:03 a.m. ET: Passengers on United Airlines Flight 93 launch a counterattack on hijackers aboard their plane, causing hijackers to crash into a field near Shanksville, Pennsylvania
• 10:38 a.m. ET: North Tower collapses
• After the reading of names concludes at 12:30 or 1 p.m. ET: A seventh moment of silence for those who died from 9/11-related health effects

The final moment of silence was added to this year's program, recognizing thousands of first responders, rescuers, recovery workers and local residents who died from health complications, in some cases years after the attacks. 

CBS News will have live coverage of the memorial events taking place at the World Trade Center site in Lower Manhattan; the Pentagon, where President Trump is attending; and Shanksville, Pennsylvania.

Prominent leaders attending the New York City events include:

The event is scheduled to begin at 9 a.m. ET, with a wreath-laying ceremony set for 10:25 a.m. 

Earlier this week, Mr. Trump held an event to honor 9/11 heroes on the Ellipse near the White House. He gave Welles Crowther, remembered as the "man in the red bandana" for his heroism on 9/11, a posthumous Presidential Medal of Freedom. 

The New York City Police Department is planning a "massive" deployment on Friday, Police Commissioner Jessica Tisch said.

"There will be layers of security that are highly visible and others that the public will not see," Tisch told reporters at a news conference Wednesday.

She said New Yorkers can expect to see uniformed officers throughout the area, along with members of the Counterterrorism Bureau, including heavy weapons teams and counter-drone teams.

Tisch told New Yorkers to expect "significant traffic and pedestrian restrictions throughout Lower Manhattan," with street closures covering a large portion of the neighborhood. New York City Mayor Zohran Mamdani encouraged the public not to drive downtown in Manhattan.

Mamdani said the ceremony at Ground Zero is not open to the general public and there will be security screenings for those invited.

The spot where the Twin Towers once stood remains a sacred space for remembering those lost in the attacks. The memorial — which includes pools of water in the footprints of the towers — is surrounded by a neighborhood brought back from devastation.

Rebuilding the area around Ground Zero after the 9/11 attacks took years, and included battles between various stakeholders with interest in the future of Lower Manhattan. Even today, 25 years later, it is still not complete.

This year's 9/11 memorial service is Zohran Mamdani's first as mayor of New York City.  

In an interview last week, he said he views it as an "enormous responsibility" at a very somber time, and he wants to make sure the day is about remembrance, not about politics. 

"It's about those that were killed that day. It's about their families. It's about the lives that have been shattered. And when you go through the museum, you see in those portraits an entire city. You see the breadth of what makes this city New York," Mamdani said, "and on these anniversaries, you have an opportunity to recognize those, to remember those."

In a silent tribute that has become a New York City tradition, the Tribute in Light returned this week to mark 25 years since the 9/11 attacks. The towering beams of light fill the night skies where the Twin Towers once stood. 

After extensive live coverage of the events on Friday, Tony Dokoupil anchors the "CBS Evening News" from Ground Zero, and then two primetime specials will spotlight stories of lives touched in different ways by the tragedy.

At 8 p.m. ET, the CBS News special "9/11: We Remember" features three stories of survival, loss and hope. "60 Minutes" correspondent Lesley Stahl will revisit a story reported by her late colleague Ed Bradley, looking at Summit, N.J., which lost nine residents in the attacks. Dokoupil talks with a family that escaped the World Trade Center with their toddler but lost their family patriarch, an FDNY hero. And Norah O'Donnell interviews the chairman of the Joint Chiefs of Staff, General Dan Caine, who shares his experience as a young fighter pilot mobilized on 9/11.

Then at 9 p.m. ET on CBS and Paramount+, "Daughters of 9/11" follows two friends who lost their fathers, Elizabeth Miller and Jessica Trant, and FBI special agent Frank Pellegrino as they confront whether the man accused of masterminding the attacks, Khalid Sheikh Mohammed, will ever face justice.

Americans view the terror attacks of Sept. 11, 2001, as a defining event — one that fundamentally changed the country.

In a CBS/YouGov poll conducted earlier this month, 68% of respondents said the attacks changed America permanently. Since the events of that day, 60% say the U.S. war on terrorism has been very or somewhat successful, while 40% say it was somewhat unsuccessful or very unsuccessful. 

Americans are roughly split on whether they think America is prepared for terrorist attacks now. Forty-eight percent of Americans say the U.S. is prepared, while 52% say the country is unprepared.
