A volunteer who fought in Syria against Islamic State has claimed British jihadists who go to other countries to fight should not be able to return to the UK as they are an "extreme threat."
Macer Gifford previously worked as a London banker but left his job in order to join the Kurdish People's Protection Units (YPG), according to Sky News.
The 30-year-old said: "As long as I live I will never be able to articulate, in person or on paper, how evil the Islamic State is. The savagery and cruelty of the Isis death cult is only truly appreciated when viewed up close."
He believes the message of hate spread by Isis is what "makes the IS foreign fighter - particularly those from the West - so incredibly dangerous."
Gifford claims those that want to come back might "claim to be disillusioned and deeply regretful", but "let's be absolutely clear, had it not been for the collapse of IS these men and women would not be coming back."
The volunteer fighter thinks many Isis militants claim to have travelled to Isis territory and got stuck due to their own naiverty - but really they hold just as many extreme views as when they first left the UK.
He suggests that allowing the fighters back would mean that the UK becomes known as a "safe haven" and instead the UK should "cut all ties with citizens that have burned their passports and declared themselves loyal to IS."
Gifford also claimed Isis spends millions purely on thinking of new depths of depravity in their propaganda, adding that the terror group has an "unprecedented" grasp of social media.
He revealed that he had seen girls chained to the ground in Isis brothels and some were as young as nine years old.
Gifford ended his statement by saying: "It was [the British Isis fighter's] choice to pursue a life of violence and murder. It is not Britain's responsibility to bring them back."
