The first details have begun to emerge of the victims of the terrorist attacks in the US.
It could be days before the final death toll - feared to include tens of thousands of people - is known.
But it seems certain there were no survivors among the 266 passengers and crew on board the four hijacked airliners.
One of the first victims to be publicly named was CNN commentator Barbara Olson, who was flying on the plane which crashed into the Pentagon building.
She locked herself in a toilet and called her husband, American solicitor-general Theodore Olson, on her mobile phone to say the plane had been hijacked by more than one hijacker wielding "box-cutters and knives".
The pilot of Flight 11, the first to crash into the World Trade Centre, was named as John Ogonowski.
