British Islamic State fighters have now moved into Afghanistan, the country's ambassador to the UK has revealed.

Said Jawad said the fanatics posed a threat not just to his country but to Britain, as they could sneak home and wreak havoc.
He said both countries' intelligence agencies were working to 'make sure they do not pose a threat if they go back to the UK', having tracked down fanatics with British passports.

The IS fighters – UK citizens of Pakistani origin – were found in the border area between Afghanistan and Pakistan. Mr Jawad told the Mail: 'It is a little easier for them to operate in that part of the world – some of them speak the language. We see them as a serious threat for Afghanistan but also the UK.'
Over the past two years IS has established a foothold in Afghanistan as its 'caliphate' has crumbled in Iraq and Syria. Its ranks have been swelled with defections from other militant groups, particularly the Pakistan Taliban.
Around 900 UK citizens are believed to have travelled to Iraq and Syria to fight with IS, and hundreds are still unaccounted for.

Mr Jawad said he did not know if the British IS fighters had come from Iraq or Syria, and could not go into details of where they were now. He added foreign fighters were using Afghanistan as a training ground, learning new skills to export terror to their home countries.
He warned: 'These people do not belong in Afghanistan, so it would be hard for them to move there forever. After a couple of months or a year, they will come back.
