A short while ago at the New York 9/11 ceremony, Terry Strada, the wife of a victim of the attacks, took a moment after reading her husband's name to call out Saudi Arabia's alleged role in the crimes.

"How can it be 25 years and still, we have no justice for the role that Saudi Arabia played in your murder?" she said at the podium, to loud applause from the audience.

The country "fomented a rancid culture of anti-American terrorism around the globe", she added.

• For context: Saudi officials have repeatedly denied that they had any involvement in the 11 September attacks, and in 2004, a US enquiry cleared the country of any involvement. Still, some family members of victims have pushed for accountability, filing a civil lawsuit that alleges the country supported al-Qaeda

The National 9/11 Pentagon Memorial is located just southwest of the Pentagon in Arlington County, Virginia, across the Potomac River from Washington, DC and commemorates the 184 people who died in the building and on American Airlines Flight 77 during the 11 September 2001 attack.

The permanent outdoor memorial opened on 11 September 2008, seven years after the attack, replacing earlier temporary memorials. In the aftermath of 9/11, a huge US flag was draped across the damaged side of the building.

The design includes illuminated benches for each victim, arranged according to their ages, from Dana Falkenberg, who was 3, to John Yamnicky Sr, who was 71, and engraved with their names.

At the 9/11 ceremony at the Pentagon, Trump is sitting beside Melania, near a uniformed member of the US Army reading the names of the fallen as a bell tolls.

To Melania's left, on the opposite edge of the stage, is Pete Hegseth and Condoleezza Rice, who was serving as National Security Adviser in the Bush administration when the attacks took place.

Others in attendance include Attorney General Todd Blanche, Education Secretary Linda McMahon, Energy Secretary Chris Wright and Dan Caine, the chairman of the Joint Chiefs of Staff.

As a young Air Force officer, General Caine was among the pilots who patrolled Washington's airspace in the wake of the attacks.

A parade of fireboats is now making its way up the Hudson River.

Several of the boats are performing a water salute, spraying red, white and blue water.

Their horns echo across the waterfront as just a short walk away, family members read the names of the thousands of people who died on 11 September.

Back at the 9/11 ceremony in New York, several former US presidents are listening to names being read out, including Barack Obama, Joe Biden, Bill Clinton and George W Bush.

As we just mentioned, President Donald Trump will be attending a separate ceremony at the Pentagon today, another site of the 9/11 attacks.

He and First Lady Melania Trump have just been seen arriving at the ceremony.

In New York, names are still being read at the 9/11 Memorial.

A second bell has sounded, and a moment of silence was just observed at New York's 9/11 commemoration ceremony.

This moment marks the exact time Flight 175 struck the World Trade Center's South Tower at 09:03 EDT that morning 25 years ago.

Away from the New York, we're expecting US President Donald Trump to appear at the Pentagon shortly, for a remembrance ceremony for those killed when American Airlines Flight 77 struck the building at 09:37 ET on 11 September.

According to the New York Times, Trump decided to pay his respects at the Pentagon rather than New York because the 9/11 Memorial's organisers do not allow speeches.

The president, however, has angrily denied those reports, referring to them in a lengthy Truth Social Post as "made up" and that he never intended to speak.

Trump attended the New York ceremony in 2024, and the Pentagon last year.

I attended the Pentagon ceremony with Trump last year. It is an extremely solemn event, held inside the inner courtyard of the building.

A total of 184 people were killed at the Pentagon on 9/11, including 59 passengers and crew on the flight and 55 active-duty service members.

The reading of the names of the victims of the 9/11 attacks has begun.

The names are being read by relatives of the victims as the cello is played in the background on this cloudy morning in Manhattan.

As the first of seven bells rang out a short while ago, honouring the first plane that hit the North Tower, large crowds of people gathered solemnly just outside barricades surrounding the 9/11 Memorial, and in a nearby park.

The area was quiet, apart from the chatter of police radio and a wailing ambulance in the distance.

A short while ago, we caught a glimpse of former presidents Joe Biden and Barack Obama in New York ahead of today's ceremony.

They were seen accompanied by former First Ladies Jill Biden and Michelle Obama.

Biden was also pictured talking to former President George W Bush, the sitting president at the time of the 9/11 attacks.

The 9/11 National Memorial in Manhattan has just heard its first bell ring, prompting a moment of silence across the assembled crowd.

This marks the exact minute the first plane, Flight 11, hit the World Trade Center's North Tower on 11 September 2001.

The annual memorial for the 11 September attacks is now taking place in New York, at the original site where the Twin Towers once stood.

US Vice-President JD Vance has also just arrived at the 9/11 memorial ceremony in New York.

He attends today without President Donald Trump, who is speaking at separate ceremony that will be held at the Pentagon later today.

As we wait for the ceremony to get under way, we've just seen some more New Yorkers and elected officials arriving, including former Governor Andrew Cuomo and current Governor Kathy Hochul.

Commerce Secretary Howard Lutnick is also there, seen wiping away tears at the memorial.

Lutnick was dropping off his son on his first day of kindergarten on 9/11, avoiding the attacks that killed all of his 658 colleagues - including his brother Gary - who were working on the 101st to 105th floors of the World Trade Center at Cantor Fitzgerald.

Taylor Blythe, 26, was just one year old on 11 September 2001.

“A lot of us were just kids when it happened. We didn't really realize the impact it would have on us until we got older,” he says.

Growing up in Iowa, Blythe says he fell in love with the fire service, inspiring him to learn more about firefighters’ sacrifice on 9/11, and after.

“Guys just going to work, doing what they do, climbing up 110 flights, knowing that they're probably gonna die, but if they can save somebody, then that's just part of their job,” he says.

“That's why every year I climb 110 flights of stairs to honour them.”

Now, he serves as a volunteer firefighter.

James Stanley, 41, is part of a group of runners who together ran from Shanksville, Pennsylvania to the Pentagon in Virginia to the Twin Towers in New York City - all the sites planes where the four planes crashed on 11 September 2001.

The total trip, organised by the Tunnel to Towers Foundation, clocks in at 485 miles (780km), run in multiple legs by participants over the course of several days. Stanley himself ran 125 of those miles - approximately one marathon per day.

As a Navy veteran of 17 years, Stanley says this is “just my way of saying thanks and remembering”.

Stanley was in high school when the 9/11 attacks happened, and he remembers watching the TV in utter disbelief after a plane hit the North Tower.

At first, he says, he thought it must have been an accident, until he saw the second plane hitting the South Tower.

He says he wants younger generations to remember that “a lot of heroes died that day".

Away from New York, leaders from across the world have also been paying their respects to those that died in the 11 September attacks.

• French President Emmanuel Macron writes on social media that the day remains "etched in the world's memory"
• Italian President Giorgia Meloni writes in her statement that "Today's anniversary reminds us that democracy and security are not taken-for-granted achievements. They are pillars of our civilization, which we have the duty to preserve together"
• Ursula von der Leyen, president of the European Commission, also shares her sentiments, recalling how "25 years ago, the world stood still". She adds: "Where the Twin Towers once stood, two columns of light now rise into the New York sky. They remind us that light triumphs even on the darkest of days"
