Theresa May: UK to deploy troops after attack, risk now critical

LONDON: Britain's armed forces will be deployed to boost security, Prime Minister Theresa May said on Tuesday, as the country raised its terror threat to the highest level of "critical" after a suicide attack in Manchester that killed 22 people, including children.

May said members of the armed forces would be positioned at key sites to free up police for patrols and military personnel might be deployed at public events such as concerts and sports events as a further attack was seen as potentially imminent.
