In late September Jihadia John the Beheader, made an appearance in a chilling video mocking men nearby who were digging their own graves. He later shot them in the head.
On Friday, ISIS released video of Jihadi John beheading British aide worker Alan Henning.
In the video Jihadi John promises to behead American Peter Kassig.
Kassig has been missing since late 2013.
Today The Daily Mail reported that drones have tracked Jihadi John in Raqqa, Syria. But British defense forces believe a strike on his camp would end in a bloody failure.
The Islamic State terrorist known as Jihadi John has been tracked by drones flying over the Syrian city of Raqqa – but British Special Forces chiefs fear a ‘kill or capture’ mission there would end in bloody failure, sources disclosed last night.
Reaper drones deployed high above the terrorists’ strongholds are also believed to have identified hostages wearing orange jumpsuits but top brass are thought to have currently ruled out a rescue operation because IS defences are too strong.
Special Forces bosses have advised the Ministry of Defence that a sustained bombing campaign lasting several weeks would be preferable.
A source said: ‘The imagery from the drones and satellites is instructive but IS infrastructure in Raqqa would have to be targeted over a sustained period to make any sort of raid a realistic possibility.
‘On the basis of our current advice there is very little chance of the Prime Minister signing off a rescue bid. The prospect of success has got to be 100 per cent or thereabouts, and at the moment it is nowhere near that. And for now there are not many other options on the table.
Raqqa is located on the north bank of the Euphrates River, about 160 kilometres (99 miles) east of Aleppo.
