Twenty years after the September 11 terrorist attacks, Americans came together on Saturday to remember the almost 3-thousand killed and reflect on how the incident reshaped the country.
President Joe Biden and First Lady Jill Biden visited all three sites, starting with a memorial event at ground zero.
President Biden did not deliver official remarks at any of the three sites, but the day before, in a speech commemorating the victims, he stressed national unity and honored those who risked their lives to rescue, recover and rebuild.
Global leaders too paid tribute on the anniversary.
British Prime Minister Boris Johnson said in a video message that though the terrorists caused grief and suffering, they failed to shake people's belief in freedom and democracy.
President Moon Jae-in also sent his condolences to the American people through social media, saying that the shock and memories left an unerasable scar on many people.
