'If I knew it would be so hard I wouldn't have come'

Azizullah left Afghanistan to seek asylum in Europe and ended up living in a freezing, derelict railway station in Serbia.

He says that if he'd realised how tough it was going to be, he would never have made the journey.

Azizullah's story is told in Exodus: Our Journey Continues on BBC Two at 21:00 on Thursday 9 November. Viewers in the UK can catch up later online.
