London tube bombing: PM says terror threat level raised to criticalGuardian/UK, Sep 16, 2017
Britain’s terror threat level has been raised from severe to critical, indicating a further attack may be imminent following the Parsons Green tube bombing, Theresa May has said.
The hunt is under way for the bomber who attempted to bring carnage to a London rush-hour tube train packed with schoolchildren and commuters.
Twenty-nine people including a young boy were injured when the bomb partially detonated and sent a ball of fire along a carriage of a District line train at Parsons Green, west London.
Police are understood to have found CCTV images that captured the bomber as he boarded the train with the bomb packed in a white plastic bucket inside a Lidl supermarket bag. The train is believed to have had onboard CCTV, and there are a large number of cameras covering the network.
Islamic State claimed responsibility for the blast, the militant group’s Amaq news agency said on Friday evening.
Nobody suffered life-threatening injuries in the incident, the fifth terrorist attack Britain has suffered in less than six months. Parsons Green station has since reopened.
In a televised statement on Friday night, the prime minister said the UK terror threat level was being raised to its highest rating and that armed police and members of the military would be seen on the streets in the coming days.
