Americans gathered on Friday to commemorate the 25th anniversary of the September 11, 2001, terrorist attacks. Ceremonies took place at the World Trade Center site in New York City, where 2,700 people died when hijackers crashed two planes into the Twin Towers.
U.S. President Donald Trump delivered remarks at the Pentagon ceremony, honoring the 184 people killed in the building and on American Airlines Flight 77, which struck the military headquarters. Approximately 140 miles away, the Flight 93 National Memorial near Shanksville, Pennsylvania, held its own ceremony. This site marks where United Airlines Flight 93 crashed after passengers and crew members attempted to regain control of the aircraft from hijackers.
