LONDON, May 23 (Xinhua) -- British Prime Minister Theresa May announced on Tuesday night that the country's terror threat level has been raised from "severe" to "critical", its highest level.
Members of the armed forces will be deployed across Britain under police command, and they would be seen at "big events" such as football matches and concerts, according to May.
May was speaking after she chaired the second meeting of the day of Britain's top-level security committee known as Cobra.
The upgrade is in response to top level reports discussed at the Cobra meeting by Britain's most senior security advisors.
A statement from the Met police about these changes will come later this evening, the prime minister added.
