People across America and around the globe have marked the 20th anniversary of the terrorist attacks on Sept. 11, 2001.
Two decades ago, the world froze as four hijacked planes slammed into the World Trade Center, the Pentagon and a Pennsylvania field. Nearly 3,000 people lost their lives.
President Joe Biden, the Obamas and the Clintons joined crowds at the National September 11 Memorial & Museum, observing moments of silence and listening as the names of those killed in the attacks were read aloud.
In the years since, foreign policy has been upended, travel and security has been reshaped, and New York City has been transformed. Tap the link in our bio to read more.
