Sky News interviewed with some extremists in Syria who say that the UK remains the largest single source of private fundraising for extremists in Syria war, outdoing countries like Saudi Arabia, Qatar and the UAE.
Sky News reported that the extremists insist they have no intention of attacking UK targets or waging war on British soil.
One of the men, identified as Mustafa, is asked directly if he is part of al-Qaeda and why he insists on hiding his identity.
"I'm not part of al-Qaeda, and I've never been a part of al-Qaeda - ever," he claimed.
This denial follows warnings from the heads of the UK's security services that young men travelling to Syria risk being radicalized before returning home to carry out terror attacks in Britain.
Fighting on a mountain top in the northeast of the country, these men look like hardcore extremists, but when they speak they are pure Brits.
Like British soldiers, they discuss kit and the best things to buy for extremism. In one exchange a young man, advised to buy new binoculars, naively asks if eBay will deliver.
The armed opposition to the Syrian government in the north of the country is now being waged almost exclusively by a myriad of extremist groups supported by a significant number of foreign terrorists from the US, Canada, Northern Europe, North Africa and the former Soviet republics of Chechnya and Dagestan.
The British contingent says their numbers are increasing daily and social networking sites are helping to organize the influx into Syria.
They know that returning to their families in the UK will be extremely difficult from now on, but in reality they probably won't get the chance - the fighting foot-soldier's life expectancy in Syria is very short once serious combat begins.
In response to Sky's exclusive report, the Foreign Office issued a statement saying: "Some people who travel from the UK to Syria for jihadist fighting will pose a security threat when they return."
Syria has been gripped by deadly unrest since 2011. According to reports, the Western powers and their regional allies -- especially Qatar, Saudi Arabia, and Turkey -- are supporting the militants operating inside the country.
The United Nations says more than 100,000 people have been killed and millions displaced due to the turmoil that has gripped Syria for over two years.
