In Photos: The Secret World Of Modern Slavery

Oksana, 46, trafficked from Ukraine into forced labour in Russia

My mother was diagnosed with cancer and needed treatment, but couldn’t pay for it. My friend suggested we find work in Moscow. A nice woman met us at the station. She said we’d be caring for sick patients for $1,000 [£765] a month. But then we were told our job was to clean a three-storey house that had burned in a fire. We were given only one meal a day, and the guards raped us like monsters. My mum died four months after I got back. She never had her operation. When she saw the condition I was in, it killed her.
