In pictures: Underground children

Henok Tesfaye came to the streets when he was 11 years old after losing his parents in a car accident. Ten years on, he is used to life on the streets.

He lives beneath a main road in an unused hole dug for telephone cables. The roof is made of concrete blocks placed side by side across a small opening.

To keep rain out, Henok and his roommate spread plastic sheets underneath old windscreens.

A small hole is both the door and the window to their tiny home.
