A Danish documentary about child soldiers in Sierra Leone and Uganda has gone viral online. It shows the grim circumstances these abducted children are forced to grow up in. The documentary also makes the claim that a British defense service company, among other western ones, employed former child soldiers from Sierra Leone to provide security for the US army in Iraq.

Danish documentary, The Child Soldier's New Job, tells the stories of children in Africa seized by militant groups. And since then, knives, weapons and death were what they grew up with.

Some children were abducted at only eight or nine years old...

The militants would kill their families to prevent them from escaping ... in order to survive, they had no choice but to live as killing machines ...

The international community has been working to rescue these African children from their horrific occupations...

But it's hard for them to resume a new life after the trauma of war... And it seems they're never quite free of the nightmare.

The documentary claims that Western private defense companies have employed former child soldiers as mercenaries.

"Several companies, Western military private companies, have been ... was from some of the poorest countries on earth," said Mads Ellesoe, documentary producer.

According to the documentary, around 250,000 children worldwide are recruited in wars.
