Ceremonies will be held in New York City, Virginia and Pennsylvania.
NEW YORK -- Friday marks 25 years since the Sept. 11, 2001, terror attacks, which claimed the lives of 2,977 people at the World Trade Center, the Pentagon and in Shanksville, Pennsylvania.
Another 9,000 people have died from 9/11-related illnesses over the last 25 years.
Victims' families, first responders and politicians will gather on Friday for annual remembrance ceremonies as Americans across the country pause to remember and reflect.
At 8:46 a.m., the first moment of silence was held at the ceremony at the 9/11 Memorial & Museum ceremony. This marks the time American Airlines Flight 11 crashed into the World Trade Center's North Tower.
Former President Barack Obama, former President Joe Biden, former President George W. Bush and their wives are at Friday morning's New York City 9/11 ceremony.
Other politicians in attendance include New York Sen. Chuck Schumer and former New York City Mayors Rudy Giuliani and Michael Bloomberg.
Vice President JD Vance is also at the lower Manhattan ceremony. President Donald Trump is instead attending the 9/11 tribute at the Pentagon in Virginia, where he's expected to deliver remarks.
In a downpour at daybreak, Defense Secretary Pete Hegseth and top military officials stood outside and watched as the giant American flag was unfurled on the building struck by a hijacked plane a quarter century ago.
President Donald Trump is set to observe Friday's 25th anniversary of the Sept. 11 attacks by attending a ceremony at the Pentagon commemorating the lives lost when al-Qaida militants hijacked planes and killed nearly 3,000 people in three locations, upending American foreign policy and national security.
It's the second year in a row for Trump to mark the day at the Pentagon.
President Donald Trump will attend the 9/11 ceremony at the Pentagon in Virginia and will not be at the New York City ceremony at ground zero, according to a White House official.
Vice President JD Vance will go to Ground Zero, an official said, adding that the three ceremonies at the Pentagon, ground zero and Shanksville, Pennsylvania, will all have administration officials in attendance.
