'Radicalisation of Young Muslims on the Rise in Cardiff, United Kingdom'

Cardiff has an ongoing problem with the radicalisation of young Muslims, said an academic who has studied the issue.

Two men from the city have been identified taking part in what appears to be a Jihadist recruiting video, which was posted online last week.

It is thought Reyaad Khan travelled to Syria with friend Nasser Muthana who also appears in the footage.

Khan lived close to the Cardiff men jailed over the London Stock Exchange bombing plot in 2012.

It is believed the two men, both 20, travelled to Syria in November, while Nasser Muthana's younger brother Aseel, 17, travelled to the country in February.

Tracking Syria Fighters Now Main Task for MI5

MI5 are devoting the greatest amount of their casework to tracking jihadists leaving the UK for Syria - and returning, as Frank Gardner reports
Tracking British jihadists fighting in Syria is now the top priority for MI5, the BBC has learned.

It comes after a video appeared to show UK jihadis in Syria trying to recruit people to join them there and in Iraq.

The Home Office said counter-terror police were working to get the video - posted by internet accounts linked to Islamic State of Iraq and the Levant (Isis) militants - taken off line.
