Calais migrant: We live like animals

Osman had been arrested and tortured in Sudan for his political activities when he escaped from a state-run hospital treating him for injuries sustained during an interrogation.

He fled to Europe by ship, where he was advised to head to Calais, France, in the hope of gaining political asylum across the border in the UK.

Now he is among a growing number of migrants living in makeshift accommodation on the edge of the city, as he explains to the BBC's Darius Bazargan.

Our World: Calais - The Final Frontier is broadcast on Saturday 31 January at 11:30 GMT on BBC World News and 21:30 GMT on the BBC News Channel.
