Watch live as the Bell of Hope rings in memory of 9/11 victims 22 years on from the terrorist attack on Monday, 11 September.
On 9 September 2001 al-Qaeda extremists seized US passenger jets and crashed them into the World Trade Center in what was the deadliest terror attack on US soil.
The Bell of Hope was presented to the people of New York by London in tribute to the thousands of people who died.
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 will be held at all three attack sites on Monday.
Kamala Harris will attend a commemoration at ground zero in Manhattan, before Joe Biden joins members of the US military and their families at a ceremony on a military base in Anchorage.
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.
