This is just another part of the conditioning and brainwashing! These people have a certain story in their head; it is Salafist with Al-Quaeda leanings. It is like when you hear your wife wants to divorce you on the wind!! Maybe you are not the best of friends today and when you go home you will remember today to put the rubbish out, and she will have changed her hair colour and style, but you are really the same. Do not think this is a new thing, just a new part of the same.
