A young member of ISIS's child soldier group the 'Cubs of the Caliphate' tells how he was groomed into the extremist organisation in a sickening new propaganda video.

The young boy says his father told him he would take him to a military camp if he 'studied hard', in the video titled The Story of Saladin.

The clip then shows the young boy cornering a man into a small room and brutally shooting him in the head.

Saladin in seen at the beginning of the video with a cast on his arm, watering plants and tending to a small garden.

'It was the last time I spoke with my father, God rest his soul,' Saladin says in the video. 'Two hours before he brought me to a military camp he told me: "You plant a tree like this. Then you must be patient. Meanwhile, learn the sharia, fear God and educate Muslims."

'Before my father was killed, which happened in battle or just before a battle, he told me: "If you study hard I'll take you to an army camp during your vacation."

'My message to the infidels is: "I am Saladin el Turkistani. I migrated to the blessed caliphate to stop people from working for tyrants, to work for God instead.

'"There's no one beside Allah. We're here only to support this religion. We're the Cubs of the Caliphate. We won't sleep, or stand erect, until we see the flag of our prophet (PBUH) in all of Allah's lands."'

The video, was obtained by the Clarion Project, opens with a black screen and the line: 'ISIS gives birth to another child terrorist.'

The Clarion Project is a Washington, DC-based organisation dedicated to 'exposing the dangers of Islamist extremism while providing a platform for the voices of moderation and promoting grassroots activism', according to its website.

Several videos released by ISIS show children as young as toddlers holding guns and promoting the extremist organisation.

When ISIS seized power in parts of Syria and Iraq in 2013 it took over schools and immediately began 'educating' children the Daesh way.

Staff were ordered to teach their extreme interpretation of the Koran and orphanages were also built, where the orphans came under the protection of ISIS commanders.

With no parents to nurture them or teach them their own morality the orphans could simply be moulded from an early age into brainwashed puppets.

Some of the schools double as military training camps.

Tens of thousands have fled the ISIS stronghold of Mosul in Iraq as Iraqi forces move in to recapture the city.

Many parents of children who lived under ISIS rule are now based at Jad'ah camp, south of Qayyarah.

In 2014 in northern Syria two Kurdish boys – aged 14 and 16 – who escaped from one of these training camps told the Daily Mail their teachers were not Syrian and could be brutal, sometimes beating them, but on the other hand the food was better than what their parents could give them.

The jihadis split the children into groups of about five and appointed a captain for each. This created a pecking order, a military hierarchy, which increases discipline.

The Kurdish parents were suspicious of the changes in their children when they returned from these camps.

Many thought the youngsters had swallowed some of the ideology. In some cases, however, it's hard for parents to prevent their sons from being taken away, not least because the jihadis pay them – money that can mean survival for the rest of the family.

The ISIS fighters believe what they preach so fiercely they are ready to die for it – and it is difficult to argue against that intensity of commitment.

The children at these camps are usually aged between seven and 15, and their parents are told that they will not be sent to the front line.

They are told they will be used in safer roles such as guarding checkpoints, sentry duty and so on but it is not true.

As ISIS has lost ground and personnel children are being rapidly promoted in all aspects of military operation.

They are made to feel comfortable around adult fighters and in military environments.

The children are also brought to relaxation centres known as the 'maqar', where jihadis unwind before going into battle.
