The White House has given details of 10 major terror plots that President Bush says have been foiled by the US and its allies since the 11 September attacks.
It is not clear how serious or advanced some of the plots were
Mr Bush cited the disrupted plans in a speech, designed to boost support for the so-called war on terror.
They include a plot to use hijacked aircraft to hit the US East and West coasts and to attack Heathrow Airport.
But the sketchy details provided by the White House make it hard to assess how serious or advanced the plans were.
Most of the plots have been previously reported in some form, but a few were revealed for the first time.
Mr Bush also mentioned five instances where targets within the US had been "cased" - including the cases of Iyman Faris who was accused of exploring the destruction of the Brooklyn Bridge in New York.
White House list of disrupted plots:
