What does the term 'ground zero' mean? Where does it come from?
In recent years 'Ground Zero' has become synonymous in the public mind with 9/11 and the attack on the Twin Towers. The term was used by news reporters in the immediate aftermath of the explosion and has stayed ever since. Ground Zero has come to symbolise the heart of the conflict between the west and Al Queda and its Islamist affiliates.
