A teenager believed to be one of three men from Cardiff to have joined the terrorist group Isis has told BBC Wales he is willing to die for their cause.

Aseel Muthana, 17, left home earlier this year to fight in Syria alongside his brother Nasser, 21.

Week In Week Out reporter Tim Rogers told Nicky Smith how he made contact with the young jihadist.
