Isil brings its atavism to the very heart of Europe
France's internal cohesion and Europe's joint stance on handling migration are at risk after Friday's act of hyper-terrorism, writes Dan O'Brien
City of light. City of slaughter. For the second time this year, gunmen have run amok on the streets of Paris, on this occasion deliberately and indiscriminately butchering as many people as they could before killing themselves.
Friday night's appalling attacks differ from those of January. The implications will be more serious too.
The most obvious difference between these attacks and those at the beginning of the year is the sheer scale of the carnage. As of Saturday afternoon, the numbers murdered were multiples of the numbers killed during the attack on the Charlie Hebdo offices and the siege of a supermarket over a few short days in January.
