New York to mark 25th anniversary of 9/11 attacks, but Trump won't attend Ground Zero ceremony

NEW YORK WILL commemorate the 25th anniversary of the devastating 9/11 attacks today with a ceremony marked by US president Donald Trump’s absence and right-wing outrage at the attendance of the city’s first Muslim mayor.

Trump will pay his respects at the Pentagon, not New York, where hijacked planes destroyed the World Trade Center and killed most of the 2,977 total victims on 11 September 2001. 

Vice president JD Vance and Trump’s four living predecessors – Republican George W Bush, who was in office during the attacks, and Democrats Joe Biden, Barack Obama and Bill Clinton – are all expected at the “Ground Zero” site in Lower Manhattan.

No one will give speeches at the ceremony, while bereaved family members will read out the names of all of those killed and a bell rung to mark major moments during the attack.

“Memorials like this and discussions about those events are an important part of keeping it alive and understanding how we prevent tragedies like this from ever happening again,” said Robert Kafka, a Chicagoan in his 60s visiting the 9/11 Memorial.

Alongside the former presidents will be Democratic mayor Zohran Mamdani, New York’s first Muslim mayor, despite a campaign urging him to stay away spearheaded by the right-wing New York Post and former mayor Rudy Giuliani.

A petition, which has gathered more than 100,000 signatures, accuses Mamdani of associating with unspecified individuals who are “dismissive of American institutions or insufficiently critical of extremist ideologies.”

“It’s concerning to me that the mayor is being treated differently simply because he is Muslim,” city council member Shahana Hanif told CNN.

Mamdani won plaudits however for recently revealing thousands of documents showing what city officials knew about toxicity levels of the air in Lower Manhattan following the attacks.

After the initial dust cloud that followed the collapse of the World Trade Center, months of pollution and lingering dust ensued, causing cancers from which thousands of New Yorkers still suffer today.

‘Toxic air’ 

“People got sick because the leaders they trusted lied and told them they were safe to breathe in toxic air,” Mamdani said Tuesday.

Nineteen Al-Qaeda operatives hijacked four planes on that day in 2001. Two jets flew into the World Trade Center’s Twin Towers, causing the iconic 110-story buildings to collapse.

A third plane struck the Pentagon, while a fourth crashed into a field near Shanksville, Pennsylvania, after passengers fought back.

Beyond those killed on 11 September, more than 9,400 other people have died from 9/11-related illnesses, according to the federal program established to provide medical care to those affected.

Some 100 million Americans were not even born or are too young to remember the tragic events.

Logan Miller (32) lost his uncle during the attacks, and his grandfather to 9/11-related illness in the aftermath.

“I think the next generation just can’t fathom what actually transpired and how someone could be impacted by that, and so I actually find them asking more questions,” he told AFP.

Minister for Foreign Affairs Helen McEntee will lay a wreath at the 9/11 Memorial later this month during UN High Level Week.

“We remember today the 2,977 innocent lives lost in the attacks, including at least 18 Irish citizens, and the multiplicity of family, friends and loved ones who continue to grieve for their loss,” she said in a statement today.

“In remembering, we recall the centuries-old bonds between Ireland and New York.

These human ties are seen through the Irish names that feature prominently on the 9/11 Memorial’s walls, the 200 claddagh rings that were found in the rubble of the World Trade Centre, and the countless stories of victims and first responders of Irish heritage that continue to be told.

Huge crowds are expected to gather in Lower Manhattan for the memorial service.

The Secret Service has erected a security ring of steel around the site of the 9/11 Memorial and Museum.

Police commissioner Jessica Tisch said an anti-drone team would be deployed as a precaution, but stressed there was no intelligence of a specific threat to the gathering.

Al-Qaeda meanwhile has marked the anniversary by releasing a video showing images of late leader Osama bin Laden and his son Hamza, who Trump said in 2019 had also been killed.

Ahead of the memorial, a drone show with 2,977 lights rose above New York Harbor, one for each person killed in the attacks.
