24 May 2017 | Written by Abheet Sethi; Edited by Mansi Motwani

British PM Theresa May said the UK terror threat level has been raised to "critical," the highest level, which means further attacks could be imminent.

The UK has deployed military personnel to protect key areas.

May said the move came after investigators weren't able to determine whether suspected Manchester Arena bomber Salman Abedi acted alone.

The suicide bombing left 22 dead and 59 injured.

No cause for alarmPM May tells citizens shouldn't be "alarmed" by troop deployment

PM May said she doesn't want citizens to be unnecessarily "alarmed," adding that the measure was a "proportionate and sensible response."

She said military personnel would be deployed at major events, including concerts, to support and work under the command of locally armed police.

The number of troops deployed would be in the hundreds, not the 5,000 figure that was reported.

DetailsHighest threat level has been reached just twice before

Britain's Joint Terrorism Analysis Centre determines the terror threat level.

In 2006, the threat level was raised to critical for the first time because of a major operation to prevent a plot to detonate liquid bombs inside transatlantic planes.

In 2007, it was raised when security personnel hunted for the suspects who attempted to bomb a London nightclub, before attacking the Glasgow Airport.
