The sickening trade in underage soldiers at camps across Pakistan was brought to light at the same time as ISIS barbarians released their latest propaganda video, featuring a youngster believed to be aged just five.
More than 200 training camps for children are reportedly being investigated by police, with each thought to be capable of holding around 200 fresh-faced recruits each.
While the camps have not been definitively linked to the warped terror network, ISIS is known to have used youngsters to boost its adult army after suffering heavy losses.
One victim of the brutal trade has told how he was snatched from the street and imprisoned by armed men somewhere near the border with Afghanistan.
The 16-year-old told the Media how he was brainwashed along with other young captives with stories about "heroes" who had become suicide bombers.
The victim, from Pakistan's second biggest city Lahore, was told his family had abandoned him and that his captors were now his family.
The claims come from an unnamed source at a south London mosque, who asked to remain anonymous out of fear of reprisals.
The contact said: "To some of those taking and holding them it's not even got much to do with extremist beliefs - it has just become a money-making enterprise.
"I have been told by two sources that you can buy a suicide bomber in Pakistan now for £30,000.
"And if the person hasn't been brainwashed into carrying out a suicide bombing, they are told their minders know where their family are and that they will kill them if they don't follow through with a bombing."
He added: "When the boy's parents spoke to the police, officers said they were aware of more than 200 of these makeshift camps which are often moved around.
"The boy estimated there were 200 held in his camp, suggesting there could be tens of thousands of victims."
Revelations about the sale of children by ISIS - also known as Daesh - come as fresh pictures were released showing how the terror group is actively seeking to recruit child fighters.
Primary school-aged children are shown in the latest images wearing camouflage clothing, holding machine guns and hiding their identity with face scarves.
The group has dubbed its youngest recruits the 'Cubs of the Caliphate' and they are taken through military training in camps in Syria and Iraq, Express reported.
