The UK terror threat level is being raised from "substantial" to "severe", Home Secretary Alan Johnson has said.
The new alert level means a terrorist attack is considered "highly likely". It had stood at substantial since July.
Mr Johnson refused to say it was linked to the failed Detroit airliner bombing, and said the government would not reveal specific intelligence details.
The home secretary stressed there was no intelligence to suggest a terrorist attack was imminent.
..are the airport scanners installed yet?
Perhaps they plan to open up some more war fronts.
