In pictures: Ground Zero two weeks on

Two weeks after the World Trade Center was destroyed in an airborne suicide attack, hope of finding any more survivors in the twisted wreckage is all but gone.

The search for survivors continues around the clock

But no-one has been found alive since the day after the attack

Salvage workers have only removed a fraction of the debris

Every piece of suspect wreckage is taken away for investigation

The rescue effort takes its toll on exhausted workers

Sniffer dogs are still being used to try to detect signs of life

Patriotism continues to galvanise the rescue effort

For some, though, the enormity of the task is all too apparent
