Parts of the network that helped suicide bomber Salman Abedi are still potentially at large even the terror threat level has been lowered in Britain following the Manchester bombing investigation, British interior minister Amber Rudd said on Sunday.
The bombing last week after a concert by U.S. pop star Ariana Grande killed 22 people.
Rudd added, “the operation is still really at full tilt in a way” and 14 people have been arrested thus far, according to numerous media reports.
The number of arrests was part of the reason why British Prime Minister Theresa May and security services in the U.K lowered the threat level from “critical” to “severe” on Saturday.
In America, Homeland Security Secretary John Kelly said on Sunday the West could continue to expect more attacks similar in nature to the Manchester bombing, but stressed intelligence agencies in the U.S. have no specific threats at the moment.
“This is just the way terrorism is today and I think it will be around for many, many years to come,” Kelly said on Fox News Sunday.
Kelly added the Manchester attack may be a result of people who were affiliated with or aiding the Islamic State, but have begun to disperse back to Western Europe because of increased fighting in the battle fronts closer to the Middle East.
