Terror Threat Weighs on U.K.
LONDON—A trip to the U.K. last summer by a suspect arrested in the Brussels and Paris attacks, Mohamed Abrini, served as a reminder about the degree to which the U.K. is vulnerable to similar terrorist atrocities.
With Islamic State’s external operations unit explicitly targeting Britain for aiding the U.S.-led coalition against the extremists in Syria and Iraq, officials privately say it is a matter of when, not if, terrorists get through. Senior British security officials also note the continuing threat from al Qaeda against the West.
But the U.K.’s long experience in dealing with terrorist threats and relatively restrictive gun laws, among other factors, provide some protection, officials and other experts say.
Mr. Abrini, who was arrested in Brussels last week, visited Birmingham, Manchester and London during a roughly weeklong trip in June and July, according to people familiar with the matter, as previously reported. They said authorities believe Mr. Abrini, who they suspect had recently been to Syria, may have been scoping out possible attack targets.
The U.K.’s most senior counterterrorism police officer, Mark Rowley, said last month that officials had discerned a shift in Islamic State’s tactics.
He said the group wanted to inflict an “enormous and spectacular” terrorist atrocity in the U.K., potentially carried out by people trained to a paramilitary level, whereas previously the plots they had seen had focused on more lone-wolf style attacks.
