The UK raising its terror threat level in the wake of recent revelations over radicalized British citizens fighting in the Middle East.
Fox News Radio's Simon Owen reports from London:
Police here saying they're stepping up patrols after the UK's threat level was raised to "severe". That's the second-highest point on a five-point scale.
Officials saying there's no evidence of an imminent attack. But British Prime Minister David Cameron says terror group Islamic State does pose a grave danger.
(Prime Minister Cameron) "We are facing a terrorist organisation not being hosted in a country, but actually seeking to establish its own terrorist state."
It's the first time the threat level here has been raised since 2010.

The UK has stepped up its terror threat level over concerns about plans being made by ISIS to attack Western targets. Does the U.S. have similar plans?
FOX News Radio's Jill Nado reports from Washington:
The increased UK terror threat is probably not going to effect the U.S., so says White House spokesman Josh Earnest...
(Earnest) "I don't anticipate that there are, that there's a plan to change that level."
And Earnest hammering home the point, the President is trying to get all the facts before making a decision about military intervention against ISIS in Syria.
(Earnest) "The President was candid about the fact that the Pentagon is still reviewing options that may be available to him."
Conservatives like Congressman Paul Ryan criticizing the President, saying the U.S. needs a strategy to finish ISIS off.
