LONDON: The threat of terrorism in the UK has been described as “smoldering” amid the potential fallout from the collapse this month of the Assad regime in Syria.

Counterterrorism police fear uncertainty about Syria’s future could fuel extremist attacks in the UK, and border officials are on high alert for the possibility that British Daesh members and supporters might attempt to return to the country.

Deputy Assistant Commissioner Vicki Evans, the UK’s national counterterrorism coordinator, said the current terror threat in the country is “smoldering” and has never been more complex, given the dangers posed by extremists, state-sponsored plots and planned attacks from individuals with no obvious ideology.

“Events in Syria are certainly something that are a focus and something that all of us need to think about,” she said.

“It’s that stark reminder that we need to focus on old enemies of peace and security as well as the new. History tells us that, unfortunately, any instability creates space for extremism, for violence and acts of terror.”

Although the British government has engaged diplomatically with Syria’s new de facto leader, Ahmad Al-Sharaa, Evans noted that his organization, Hayat Tahrir Al-Sham, remains a banned terrorist group under UK law and anyone who demonstrates support for it could face terror-related charges. She said no one has been arrested so far for such activity but would neither confirm nor deny whether anybody is under investigation.

Evans also revealed that counterterrorism police are increasingly finding images of extreme violence, pornography, misogyny and gore, which sometimes fuel terror plans, in the online viewing histories of suspects as young as 10 years old.

“It’s a pick-and-mix of horror. These sorts of grotesque fascinations with violence and harmful views that we’re seeing are increasingly common,” she said.

“We most definitely need to think differently about how we stop that conveyor belt of young people who are seeing and being exposed to this type of material and, unfortunately, sometimes then going on to commit horrific acts.”
