Britain has raised the terror threat level to critical following the suicide bombing at the Manchester Arena.

British Prime Minister Theresa says this means further attacks may be imminent.

May says investigators are unable to rule out whether Manchester bombing suspect Salman Abedi acted alone.

Military personnel will now be deployed to protect key sites.

Twenty-two people were killed and 59 injured when a suicide bomber attacked Manchester Arena last evening.

The British prime minister also confirmed the government has triggered "Operation Temperer", a long-standing emergency plan to put soldiers into key public locations to support armed police in protecting the public.

She says military personnel may also be seen at other events over the coming weeks, such as concerts and would work under the command of police officers.

The prime minister says she didn't want the public to feel "unduly alarmed" but says it is a "proportionate and sensible response".

She says the government will take every measure available to help the police protect the public.
