On September 11, 2026, New York City observed the 25th anniversary of the 9/11 terrorist attacks, which dramatically altered global security and politics. Nineteen operatives from the terrorist group Al-Qaeda hijacked four commercial airplanes in the morning of that clear day in 2001.

Two of the jets were deliberately flown into the Twin Towers of the World Trade Center in Lower Manhattan, skyscrapers that stood 110 stories tall. The impacts caused catastrophic damage, leading to the collapse of both iconic structures.

The attacks resulted in almost 3,000 deaths, injuries, and profound trauma. Around the world, they triggered extensive counter-terrorism policies and military operations.

For the 25th anniversary, New York authorities implemented tight security to safeguard memorial gatherings and honor the victims with reflective ceremonies. Public officials and survivors gathered to pay tribute to those lost that day.
