In pictures: Ethiopia's remote people

During holidays, Surma children paint their faces and bodies with chalk.

“When our parents finish harvesting the maize, they make bonfires and sing and dance around them.

"During these nights we see many stars and the Milky Way, which looks like a plane.

"So we take chalk and put dots, looking like stars, on our bodies”, one boy said.
