British authorities are searching for suspects in the London subway blast that injured more than two dozen people as hundreds of soldiers are being deployed across the country.
Authorities increased the terrorism threat level to “critical” late Friday, after a bomb partially exploded during the morning rush hour, meaning a government task force believes another attack may be imminent.
The soldiers will add to the police presence Saturday at public places to deter attacks after the blast on a District Line train. No arrests have been made. The explosion and an ensuing stampede at Parsons Green station injured 29 people. None of the injuries, some of them burns, were believed to be life-threatening.
The bomb was put into a bucket and concealed in a shopping bag.
