Britain raised its terror threat level to critical, meaning a new attack is believed to be imminent and soldiers are being deployed to assist armed police. <br/><br/>British Prime Minister Theresa May said that it is a possibility we cannot ignore that there is a wider group of individuals linked to this attack, after a suicide bomber killed 22 people, including children, at a pop concert late Monday in Manchester. <br/><br/>Addressing the nation from her Downing Street residence, May said armed police who would usually protect strategic points would be replaced by members of the armed forces under Operation Temperer. <br/><br/>The terror threat level was previously set at severe, which means an attack is highly likely. A critical level means an attack is expected imminently.
