Irish who died in 9/11 remembered

Many tributes are taking place to mark the 25th anniversary of the deaths of those who were Irish or of Irish extraction in the 9/11 terror attacks.

At least 18 were Irish citizens while many of the first responders who perished in the attacks were of Irish extraction.

An event took place in Ballymote, Co Sligo on Friday. Among those who remembered was Anne McHugh from Tuam, Co Galway who died in the Twin Towers attack.

On Saturday Fr Mychal Judge, the first designated victim of the Twin Towers attack, will be remembered in his father’s home village of Keshcarrigan, Co Leitrim.

Former vice-president Mike Pence, former New York City mayor Michael Bloomberg, and former UK prime minister Tony Blair have all remembered 9/11

“On this solemn anniversary of September 11th, let us remember the 2,977 innocent souls who perished at the hands of our terrorist enemies,” Pence said.

“And let us also honor those who gave their lives in the long struggle that followed.”

Bloomberg, who is also the chairman of the National September 11 Museum and Memorial, said the sky was crystal clear and bright blue on 9/11.

“I had just cast my ballot when I heard that a plane had hit the World Trade Center,” he said. “In the face of unimaginable tragedy and loss, New Yorkers and people across the country responded with bravery, resilience and hope.”

Blair, who was the UK prime minister at the time, said in a video statement that “that day changed the world”.

“The struggle against terrorism in all its form continues,” he added.

Families remember 25 years on

Families returned to the World Trade Center on Friday to mark 25 years since the 9/11 terror attacks.

Mourners and survivors gathered around the twin waterfall pools that mark the footprints of the two towers in Lower Manhattan for the somber ceremony.

Joining for the day of remembrance were vice president JD Vance, New York mayor Zohran Mamdani and former mayors Rudy Giuliani and Michael Bloomberg.

All of the living former US presidents were also in attendance: Joe Biden, Barack Obama, George W. Bush and Bill Clinton.

The 17-minute period between when the north and south towers were hit by hijacked planes defined an era and a nation, and 25 years later, an estimated 100 million Americans — nearly 30 per cent of the population — are too young to remember that day.

During the reading of names, young family members mentioned aunts and uncles they never got to meet, and parents referenced grandchildren who never got to know their grandparents.

The square manmade waterfalls at the memorial plunge 30 feet, a design which their architect has described as “absence made visible.”

There were moments when there was a notable shift in tone during what is typically a hallowed ritual, as some accused successive US administrations of not holding Saudi Arabia to account for its role in the attacks.

“Today we renew the sacred oath, we will never ever forget,” he said. “That’s why we fight today.”

For the first time, this year’s Lower Manhattan ceremony includes an acknowledgement of how the toll of the attacks is still growing.

After the reading of the names, a seventh moment of silence will be observed, honouring those who died years later from illnesses and injuries linked to the aftermath of the attacks.

It is a recognition that even as the morning the twin towers collapsed passes from living memory for more Americans, its consequences are still unfolding - Bloomberg

9/11 remembrance includes those who died from illnesses afterwards

The annual 9/11 remembrance ceremony in New York included an additional moment of silence for those who died from illnesses contracted after the terrorist attack.

The ceremony at Ground Zero previously had six moments of silence, now a seventh has been added.

New York mayor Zohran Mamdani claimed this week that more people died as a result of illnesses related to the attacks than the 2,977 killed on 9/11.

These included those injured or traumatised in the attacks but also those who died from the toxins released by the thousands of tonnes of debris.

The dust plume included concrete, deadly asbestos and glass which fell all over Lower Manhattan. Many first responders developed respiratory illnesses, cancers and mental illnesses at a rate which far exceeded normal expectations.

Mamdani released documents related to air quality that showed the air around the fallen Twin Towers remained toxic for much longer than officials claimed at the time.

Joe Biden and Hilary Clinton reflect on the 25th anniversary

Former US president Joe Biden shared some words on social media honouring the victims and first responders killed on 11 September.

Biden attended mass at St Patrick’s Cathedral on Thursday to mark the 25th anniversary of the 9/11 attacks.

Despite having stage four prostate cancer, Biden stayed for an hour after the service speaking to the families of those who were bereaved.

On X on Friday morning, he posted: “This morning, Jill and I hold close the families who carry that loss every day. We honor the heroes of September 11th: the firefighters and police officers who rushed into the towers and the Pentagon, the passengers who fought back over Shanksville, and the generation that stepped up to serve in the aftermath.”

Hillary Clinton, the former US secretary of state, said “the consequences have continued for 25 years”, and it’s our job to inform younger generations who are too young to remember the attacks.

“Something worth remembering 25 years after 9/11: in the aftermath of catastrophe, people look around, they see what is needed, and they help.”

Addressing the crowd at the Pentagon’s commemorative ceremony, US president Donald Trump said, “in 25 years, a generation has passed since the terror attacks.”

“Yet time has not dimmed the honour of that day our country came face-to-face with true evil.”

“Today we renew the sacred oath that we first swore in their names a quarter of a century ago,” he said.

“We will never, ever forget. That’s why we fight today.”

“On days like 9/11, we learn what a country is truly made of”.

“We’re learning right now what we’re made of and we have to be strong and we have to be smart,” he added.

The president said the US will never be the same after the events of September 11th, 2001.

“We were all New Yorkers that day,” he said, of September 11th. “But we’re also all Americans.”

“We salute the service members working right now to ensure the world’s number one sponsor of terror, the Islamic Republic of Iran, will never, ever have a nuclear weapon,” he said.

Speaking at the Pentagon, Dan Caine, the chair of the joint chiefs of staff, said “today is not just a story of loss; it is also a story of great American courage, selfless service, and those who’ve made the choice to carry those memories forward.”

“The courage of those extraordinary Americans in Pennsylvania, in New York, and right here on these hallowed grounds did not end when the smoke cleared and the fires went out, because survivors and families have carried it forward through service, through sacrifice, and through remembrance.”

Pete Hegseth, the current defense secretary and Condoleezza Rice, the former secretary of state, also spoke at the ceremony.

In a post on X, Taoiseach Micheál Martin wrote, “today we honour and remember all those who lost their lives during the September 11th attacks, a day of unspeakable horror that shook the world.”

He said of the victims, at least 18 were Irish citizens and an estimated 1,000 were of Irish heritage.

“It was an attack on all humanity, on democracy and the values we all share.

He said it was strongly felt in Ireland due to the “close bonds between our two nations and people.”

“We remain united with all the survivors of 9/11, both today and in the years to come. We will not forget them.”

On this day 25 years ago, the Ladder 3 crew sat at the maple table, having breakfast, writes Washington correspondent Keith Duggan.

They had less than two hours to live. Eight in the morning is a hectic time, with the night tour crew clocking off and the morning tour unit already arrived.

Officially, the tour, or shift, hours are 9am-6pm and 6pm-9am, but Ladder 3 had an inherited tradition where the morning crew would arrive a few hours before the shift officially started.

Seventh moment of silence added to New York commemoration

A new moment of silence, honoring all who have died from the health effects of 9/11 and its aftermath, will be added to the annual commemoration ceremony in New York.

For the past 24 years, the 9/11 commemoration has included six moments of silence to mark the times when each of the World Trade Center towers was struck, when each tower fell, and the times corresponding to the attack at the Pentagon and the crash of United Airlines Flight 93 in Pennsylvania.

Since 9/11, thousands of first responders, rescue, recovery and relief workers and lower Manhattan community members have died from 9/11-related illnesses.

The seventh moment of silence will become a permanent part of the annual ceremony.

There are few more enduring images of the terrible events of 9/11 than those of New York firefighters pulling the body of Fr Mychal Judge from the remains of the Twin Towers, writes Ronan McGreevy.

Where others fled the collapsing towers, Judge remained at post to give the last rites to the firemen on site. He was in the lobby of the North Tower praying for victims when the South Tower collapsed, burying him under the rubble and killing him.

The photograph of Judge was taken by Reuters photographer Shannon Stapleton, who was in the area on another job when the attacks happened. It was one of the first photographs taken after the towers collapsed.

Judge, a Franciscan priest, became known as Victim 0001, of 9/11, of the 2,603 people who died when two hijacked planes crashed into the Twin Towers on the morning of September 11th, 2001.

When American civil and political leaders gather at the 9/11 memorial in New York on Friday, their focus will properly be on the almost 3,000 people who were murdered in the attacks 25 years ago, writes China correspondent Denis Staunton.

But after the commemoration is over, they might also reflect on the millions of others around the world whose lives were destroyed by the United States’ response to the events of September 11th, 2001.

More than 940,000 were killed directly by post-9/11 war violence in Afghanistan, Iraq, Syria, Yemen and Pakistan, almost half of them civilians, according to the Costs of War project by the Watson School of International and Public Affairs at Brown University.
