Mohamed Lamin Slot, 26, ambulance driver. Pictured in the desert near Rabouni refugee camp: 'I was born in El Aaiun camp in 1983. I grew up here, we got accustomed to it. I studied in Algeria for six years. I started working as an ambulance driver in 2005, it is a great job and I like it. There is a lot of tiredness but I like to help people. It took one year to train in first aid, it was very difficult at first, you remember many bad things like blood and injuries but now it's normal for me. We never rest there are always emergencies, maybe there are eight or nine cases per day. I work from Saturday to Friday and work the whole week even sleeping in the hospital, then I have the following week off. I get almost no sleep during that week. The hardest thing is when people die on the way to the hospital, you wish you could have got them there but you couldn't.'..
