World trade centre Collapses by attack (11/09/2001)


Smoke billowed out of the World Trade Center after the first plane hit it


Less than 18 minutes later, another plane closed in on the other tower


The plane seemed to swerve to hit the other tower


The second plane caused a massive explosion and fire on the second tower


The South Tower collapses in a cloud of debris and smoke


The collapse obscures much of downtown Manhattan


The collapse of the second tower, the West Tower, followed shortly afterwards


Terrified survivors try to flee, stumbling through a fog of smoke and shredded debris from the collapsed towers


Across the river from Manhattan, crowds watched the drama unfold in stunned silence


Shocked people at St Patrick's Cathedral watch the World Trade Center collapsing


Emergency services rushed to evacuate lower Manhattan and rescue casualties before the towers collapsed


Police, firefighters and paramedics were close to the towers when they collapsed


The Pentagon was also hit - by some sort of aircraft - minutes after the World Trade Center explosions


George Bush was told the news as he spoke to children in a Florida school


Smoke was visible across the whole of Manhattan island
