I was a doctor in Aleppo, now I make £60k a month smuggling migrants

Abu Mahmoud is richer than he has ever been, even when he was a doctor in Aleppo. Smuggling Syrians into Europe has made him $100,000 (£60,000) this month alone. But it is not an easy life.

He is, for one thing, busy. An interview in an Istanbul cafe takes hours, as it is interrupted by constant calls to his three mobile phones.

The cafe is on a main thoroughfare busy with Turks walking home from work and thousands of refugees, who gather in the plaza around the Metro station and in a nearby park.
