Britain plans for 'severe' Olympic terror threat




LONDON (AP) -- Britain is planning for the terror threat to be "severe" during the 2012 London Olympics despite the level being downgraded this week.

Home Secretary Theresa May announced Monday that the assessment of a terrorist attack had been lowered from "severe" to "substantial." The new alert level meant that the risk of an attack is a "strong possibility" and may occur "without further warning."

But Olympics minister Hugh Robertson said Tuesday that the "planning assumption" for the games is that the threat will remain at severe -- the second-highest classification, meaning an attack is highly likely in Britain.

There are five levels of threat, from low, meaning an attack is unlikely, to critical, meaning an attack is imminent.
