Five survivors pulled from wreckage

Five people have been pulled alive from the wreckage of the World Trade Centre.

Three of the survivors are police officers.

A Brooks Brothers clothing store has become a morgue, where workers bring any body parts they find.

Workers using bulldozers and shovels are investigating claims of mobile phone signals being received from the wreckage.

The devastation has turned the concrete canyons of lower Manhattan into a dust-covered ruin of girders and boulders of broken concrete.

Cranes and heavy machinery are being used, gingerly, for fear of dislodging wreckage and harming any survivors.

New York Mayor Rudolph Giuliani says the best estimate is a few thousand victims will be left in each building.

The rubble at the trade centre has been taken by boat to a former Staten Island rubbish dump, where the FBI and other investigators are searching for evidence.
