President Joe Biden has commemorated the 20th anniversary of the September 11 attacks on the US with visits to each of the sites where hijacked planes crashed in 2001, honouring the victims of the devastating assault.

In the first of his wordless tributes, Biden stood in sombre silence with former presidents Barack Obama and Bill Clinton at the New York City site where planes brought down the World Trade Centre's twin towers.
The Bidens then flew to Shanksville, Pennsylvania, before heading back to the Washington area to visit the Pentagon memorial.
"The core of who we are is not divided," Biden said on Saturday during a visit to a fire station after the Shanksville ceremony.

Nearly 3000 people died in the attacks in New York, at the Pentagon and in Pennsylvania, where passengers on United Flight 93 overcame the hijackers and the plane crashed in a field, preventing another target from being hit.
Here are some of the day's images as the US came together at sites across the country to remember all those who died.
