On Monday, Americans gathered to commemorate the 22nd anniversary of the 9/11 terror attacks, which resulted in the loss of nearly 3,000 lives and had a lasting impact on the nation. Memorials were held at the sites of the attacks, as well as in other parts of the country, and President Joe Biden marked the anniversary with a visit to the Pentagon Memorial. The 9/11 attacks remain the deadliest terror attack on U.S. soil, and Americans remember the victims and the lasting impact of the tragedy as they commemorate the anniversary.
