MI5 is on high alert amid fears that Isil fanatics are already plotting revenge attacks for the reported killing of Jihadi John in a drone strike in Raqqa, Syria.  The communications of known sympathisers are being monitored closely as surveillance is stepped up to prevent a terrorist outrage in revenge for the operation which is now widely acknowledged to have resulted in the death of Mohammed Emwazi– who as Jihadi John – earned global notoriety.  In a separate development the Telegraph has also disclosed that Jihadi John has fathered a son who is entitled to British citizenship and could be brought to live in the UK..  The identity and nationality of the boy’s mother is not known, but as a British citizen, Emwazi will pass his citizenship onto his child.  #Raqqa the good thing is #JihadiJohn got killed near Clock tower where #ISIS Execute people #Syria #IS #ISIL pic.twitter.com/dcVlbd8OJq  Although one or two officials in Washington are counselling caution, there is now an overwhelming consensus that Jihadi John was killed in the drone strike along with a sympathiser – possibly his driver – as their car hurtled through the Syrian town of Raqqa.  Gradually details of how the British Jihadist was tracked down and then attacked by drone has started to emerge.  A British drone, operating from Lincolnshire, helped track Emwazi, although what are believed to have been the fatal shots were fired by the Americans. According to one report he was tracked for six weeks before the decisive strike was made.  Jihadi John is almost certainly dead. But was the manner of his killing a morally correct one?  At various times reports have said that Jihadi John was “evaporated” or “incinerated” and “eviscerated” during the strike.  In a separate development, there were reports that the Turkish authorities had captured his closest associate, Aine Lesley Davis, who is also a Briton.  Reaction to the death of Emwazi has varied. Col. Steve Warren, the Pentagon spokesman, was jubilant.  “He was a primary recruitment tool for that organization. We’re all familiar with the ghastly videos- the absolute barbarism that he displayed against American citizens. I mean this guy was a human animal, and killing him is probably making the world a better place.”  But the families of his victims were rather less triumphant. Dragana Prodanovic Haines, the Croatian wife of David Haines, a British aid worker, said the Jihadist’s death would mean one monster less, but she still wished he had been captured alive.  “"I have heard the news but it doesn't bring me any comfort because nothing will bring back my husband.”  Diane Foley, the mother of murdered American journalist James Foley, found no solace in Jihadi John’s death..  “It saddens me that here in America we are celebrating the killing of a deranged, pathetic young man,” she told ABC News.  Look, why couldn't the police just go an arrest Emwazi? It's not as if it's a really dangerous war zone & I'm sure he'd have come quietly.  The death of Emwazi has also had political implications in Britain, with Jeremy Corbyn, the Labour leader, wishing Jihadi John had been captured alive and put on trial – a view which was not shared by some of his MPs including Ian Austin.  Mr Austin ridiculed the suggestion that Emwazi would have come quietly.

He was shown in those sickening videos of the beheading of British aid workers.  "He posed an ongoing and serious threat to innocent civilians not only in Syria, but around the world and in the United Kingdom too.  "He was Isil's lead executioner, and let us never forget that he killed many, many Muslims too.  "And he was intent on murdering many more people.”
