The Bell of Hope rang in memory of 9/11 victims 22 years on from the terrorist attack on Monday, 11 September.
Around 3,000 people from over 90 nations, including 67 from the UK, were killed when the terrorists flew the planes into the Twin Towers in New York City and the Pentagon, and another crashed into a field near Shanksville, Pennsylvania.
Commemorations were held at all three attack sites on Monday.
The bell rings at 8:46am local time every year, representing the time when the first plane crashed into the North Tower of the World Trade Center.
