Insight - Path to jihad: from upscale Cairo to Islamic State beheadings

CAIRO (Reuters) - After leaving his upscale Cairo neighbourhood to fight with the Islamic State militant group in Syria and Iraq, Younes says he learned how to work as a sniper, fire heavy weaponry and behead prisoners using the proper technique.

One year later he harbours the kind of ambition that could create a security nightmare for Egyptian authorities: to return home and hoist the Islamic State's black flag in Egypt as his comrades have over large swathes of Iraq and Syria.
