(NewsNation) — The United States is commemorating the 24th anniversary of the deadly Sept. 11, 2001, attacks with memorial ceremonies and moments of silence Thursday.

Whether at ground zero in New York City, the Pentagon or a rural field near Shanksville, Pennsylvania, millions across the country are expected to honor the nearly 3,000 lives lost during the coordinated terrorist attacks.
