The rescue effort in the wreckage of the World Trade Centre was temporarily called off tonight as fears mounted that another building may collapse.
One Liberty Plaza, a 743-foot tall, 54-storey building, was under threat of toppling after a partial collapse of the building, rescue officials confirmed.
An immediate evacuation of rescue workers and people close to the scene was put in place because of the risk as windows and parts of the outside of the building could be seen peeling away.
The building was beside the destroyed twin towers but had apparently survived the initial destruction. The evacuation came as fears had also mounted for the safety of Number Five World Trade Centre, a smaller office block which was part of the complex.
It had suffered a partial collapse when the twin towers fell and rescue officials were risking their lives by working on top of it to gain access to the scene of devastation.
