A stabbing at church in Spain last week has put security agencies all over Europe on alert over the recurrence of “low intensity” jihadism. Their main fear resides in the Islamic State's (IS) potential revival, whether in northeast Syria or among its detainees in European jails, that might fan its embers, a complex issue where the continent's foreign and domestic policies are being challenged.
The stabbing at a church during evening Mass in Algeciras, a coastal city in southern Spain, was carried out by a 25-year-old Moroccan man who killed the sexton after destroying crosses and religious images.
