Saturday September 11 will mark 20 years since the world stood still and watched on in horror as the 9/11 terrorist attacks played out on TV screens around the world.

19 men hijacked four commercial airplanes on the morning of September 11, 2001 and travelled towards major US landmarks in an attack orchestrated by al Qaeda leader Osama bin Laden.

2,753 people were killed at the World Trade Center in Lower Manhatten, New York, when two flights intentionally crashed into the north and south towers.

184 people were killed at the Pentagon in Washington when American Airlines flight 77 crashed into the building.

40 passengers and crew died near Shanksville, Pennsylvania when a flight crashed into a field.
