UK lowers its national threat level to 'severe'
British officials have lowered the country's official terrorist threat level from "critical" to "severe" following the arrest of a second man in the London subway bombing.
Home Secretary Amber Rudd said Sunday that this is an indication that "good progress" is being made into the investigation of the Friday attack on a London subway train that injured 30 people. She cautioned that it is still an ongoing investigation.
The "severe" threat level now in place means officials believe another attack is highly likely. When it was set at "critical," that meant authorities judged an attack to be imminent.
The threat level is set by the Joint Terrorism Analysis Center.
