Particularly, UK law enforcement and armed forces will move forward on the assumption that the threat level is "critical," according to May's orders.
On Monday, a suspected-terror attack struck attendees at Manchester Arena following the conclusion of an Ariana Grande performance. A loud blast went off that a UK man reportedly captured on his dash cam. Ultimately, 22 were killed, some of whom were children, while dozens more sustained "shrapnel" injuries.
A suicide bomber set off a blast in the foyer of the venue that held more than 20,000 concert goers.
The incident spurred a nationwide shutdown of all campaign activities. A general election is scheduled for June 8. May's critics alleged that the Manchester Arena incident is strangely beneficial timing for the politician.
Debbie Hicks, vice chairman for the UK Labour Party, excalimed, "I can't help thinking this is wonderful timing for Theresa May… it is well known that politicians use events as part of their campaigns or messages."
