Sources: 1044. Developments: 23. As the 25th anniversary of the September 11 terrorist attacks arrives, the United States and the international community are engaged in widespread commemorations. The attacks, which killed 2,977 people, are being marked by official ceremonies at Ground Zero, the Pentagon, and Shanksville. In New York City, tributes include the ‘Tribute in Light’ and a drone show, ‘2,977 Lights Over New York Harbor,’ where 2,977 drones formed the silhouette of the Twin Towers. National leadership is represented by Vice President JD Vance and former presidents Joe Biden, Barack Obama, George W. Bush, and Bill Clinton in Manhattan, while Donald Trump is attending ceremonies at the Pentagon. President Trump also issued a proclamation declaring the day ‘Patriot Day,’ calling on the nation to renew its vow to ‘Never Forget.’ For the first time, a seventh period of silence honors the 453 FDNY members who died from 9/11-related illnesses, alongside the 343 firefighters who died on the day of the attacks. International responses include the United Nations describing the attacks as an ‘attack against humanity’ and NATO Secretary General Mark Rutte reaffirming alliance unity. Indian Prime Minister Narendra Modi expressed solidarity with victims' families, noting India’s own experience with cross-border terrorism. Reflecting on the quarter-century since the attacks, former President George W. Bush, speaking at his presidential library alongside former Secretary of State Condoleezza Rice, warned against isolationism. Discussions also highlight the human cost of the subsequent ‘war on terror,’ with Brown University’s Cost of War project estimating between 4.5 and 4.7 million direct and indirect deaths. In Afghanistan, the return of Taliban rule in 2021 has raised concerns regarding the status of women, with activists urging continued international engagement. ## Claims - The September 11 attacks resulted in 2,977 deaths.
