Police and migrants clash in Calais
An increasing number of migrants are arriving in Calais, northern France, in the hope of entering the UK.
Tensions between them and the CRS riot police are high - in this incident, as the BBC's Darius Bazargan reports, a rumour of police brutality spirals into a large-scale confrontation between migrants and police.
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.
