American mother of three joins Kurdish militia fighting Islamic State jihadists

In the months before joining a militia to battle Islamic State of Iraq and Levant (Isil) jihadists, Samantha Johnston had led the life of a gregarious and adventurous small town girl.

The 25-year-old mother of three from Emerald Island had joined the US military but never served overseas. Instead, she travelled on her own initiative, posting on her Facebook pictures of herself bikinis from beaches in Japan.
