So, this happened... Via The Scotsman: ISLAMIC extremists are threatening to kill Scottish aid worker David Haines to help secure a Yes vote in the independence referendum, an intelligence expert has claimed.

Mr Haines was paraded by Islamic State fighters in a video last week following the second beheading of a US journalist. A macabre video makes it clear the 44-year-old from Perth could face a similar fate.

Professor Anthony Glees of the Centre for Security and Intelligence Studies at the University of Buckingham said: "ISIS are masters of propaganda and realise the impact of selecting a Scot.

"They will hope by showing the UK is weak and unable to defend its citizens it will drive Scots to embrace independence.
