Sunday newspapers carried details about the recruitment video appeal by young British and Australian Muslims fighting with the extremist Isis group in Syria and Iraq. The newspapers carried interviews with some of the identified militants. The Mail on Sunday focuses on one man, 20-year-old Reyaad Khan from Cardiff, showing a picture of him as a young teen among friends in his Welsh school. It asks “What turns this boy from a leafy British suburb into a terrorist?” The paper traces his changing life by examining his Facebook posts, which start as a sport-loving teenager, complaining about homework and posing with a family pet, and end as a young man “revealing his increased fanaticism” in “rants” about Isis and its increasing control of parts of Iraq.
