The mobile phone is a remarkable piece of engineering. But look inside. There's blood in this machine.

There's blood in this device because your mobile contains tiny electronic circuits, and they couldn't work without mineral called COLTAN.

It's mined in the eastern Congo. There is blood here, the blood of Congolese who are dying in a terrible conflict.

The West’s demand for Coltan, used in mobile phones and computers, is funding the killings in Congo. Under the close watch of rebel militias, children as young as ten work the mines hunting for this black gold.

Blood Coltan exposes the web of powerful interests protecting this blood trade. Meet the powerful warlords who enslave local population and the European businessmen who continue importing Coltan, in defiance of the UN.
