The White House says there is no credible, specific intelligence about any imminent terrorist threat against the United States.
White House spokesman Tony Fratto made the comment Wednesday in response to remarks Tuesday by U.S. Homeland Security Secretary Michael Chertoff that the U.S. is at greater risk for attacks over the next months of summer.
Chertoff said he based the remark on a "gut" feeling after taking into consideration the pattern of summertime terrorist activity.
He made the comments to the editorial board of the Chicago Tribune newspaper.
He also warned Americans against complacency, saying they should be on heightened alert after recent terrorism episodes in Britain. Late last month, two unexploded car bombs were discovered in London and a flaming vehicle was rammed into an airport terminal in Glasgow, Scotland.
The White House says administration officials will hold a homeland security meeting Thursday, but says that it is a routine session.
Some information for this report was provided by AFP, AP and Reuters.
