America is preparing to mark the 10th anniversary of the 9/11 terrorist attacks, with events taking place across the globe to remember the worst attack on US soil in history.
Thousands will gather at ceremonies at the site of the destroyed World Trade Center towers, at the Pentagon, and in a field in Pennslyvania where the fourth hijacked plane crashed.
President Barack Obama and former president George Bush, who was leading the country at the time, will lead the remembrances for the 2,977 people who died.
New York's 650lb Bell of Hope, which hangs near Ground Zero in St Paul's Chapel, the rest centre for 9/11 rescue workers, will sound at 8.46am New York time, the moment of the first impact.
The two presidents will join victims' families to hear the reading of the names of those who died as bells toll across the city and President Obama will also visit the other two sites.
The remembrance takes place in the shadow of the "credible" threat of a terror attack on the mainland US as other ceremonies begin to take place around the globe
