It's getting tense. Just checked out the link and thought I share couple of the main points in the article posted.
"Britain launched a new security alert system on Tuesday, ranking the terrorist threat to the country as "severe" and saying an attack was highly likely.
It was the first time the government had published such information. . . ."Severe" is the second highest level."
