Monday night’s murderous gunman in Vienna is officially described as ‘Islamist’. Brahim Aioussaoi, the man accused of murdering worshippers in a Nice cathedral last week, arrived (reported the BBC) with ‘three knives, two phones and one Quran’. These would seem to be the basic toolkit required. A friend who lives in southern France tells me that although the latest lockdown measures prevent church services being held, so serious is the terrorist threat to churches that many are guarded by police.
