The autistic Russian teenager amazing the art world

When Markus was diagnosed with epilepsy and autism as a baby, his mother refused to put him into a care home, despite pressure from doctors.

Inspired by her love, Markus started painting - astonishing his mum with his artistic talent.

Now the 13-year-old's artwork is exhibited around the world, and sells for thousands of dollars.

Markus's mother Natalya spoke to the BBC Russian Service about his talent.
