COSTELLO: All right. As promised, more on the breaking news this morning. The British terror threat has been raised to severe. That means, that seems to mean that an attack is eminent, although there is no specificity as to what that attack might be. So, let's head out to London and CNN's Erin McLaughlin to tell us more about this. Good morning.</s>ERIN MCLAUGHLIN, CNN CORRESPONDENT: Hi, Carol. That's right. British Home Secretary Theresa May within the last hour releasing a statement raising the alert level from this country from substantial to severe -- meaning a terrorist attack is, quote, "highly likely". Now, the statement goes on to say that there is no information to suggest that an attack is imminent and that this decision is based on the latest intelligence. Now, statement also goes on to say that this is related to developments in Syria and Iraq where, quote, "terrorist groups are planning attacks against the West", likely to involve foreign fighters who traveled there from the U.K. and Europe. And we know that there are estimated to be between 400 and 500 British jihadist in Syria and possibly have crossed into Iraq, that this government has been very, very concerned about what could possibly happen if those jihadists decide to return back to the United Kingdom -- Carol.</s>COSTELLO: So, what precautions is the government taking there?</s>MCLAUGHLIN: The moment that is not clear. We're getting this initial information, but the fact that the terror level has been raised in this country is an indication that certain precautions, certain security measures across the country need to be taken, need to be heightened and, again, this is the first time that this kind of alert has been raised in the past several years, Carol. So, officials here in the United Kingdom, no doubt, taking this extremely seriously.</s>COSTELLO: All right. I'll let you get back to reporting. Erin McLaughlin, many thanks to you. We'll be right back.
