Under supervision by militants, he was taught the Quran, trained in the use of weapons and forced to watch men being crucified and women stoned to death.

He was also made to take oaths of allegiance to ISIS leader, Abu Bakr al-Baghdadi, and witness boys younger than himself being ‘brought to the camp and lashed’.

Today, Mohammed, who was eventually pulled out of the camp after 30 days by his father and later fled to Turkey with his family, described some of his horrific experiences there.

‘When we go to the mosque, they order us to come the next day at a specific time and place to [watch] heads cut off, lashings or stonings,’ he told CNN.
