A girl migrant has told the BBC how she travelled alone from Iran to Greece for two weeks, despite being just 12 years old.

The girl, who told the BBC's Matthew Price she is from Afghanistan and was living in Iran with her parents, said she had chosen to head for Europe because the Iranian government "has very bad behaviour with us".

"I saw my situation, I can't go to college, I can't study, you're not a human, you are worse than animals even," she said.
