Britain's new law allowing the deportation of undocumented asylum seekers to Rwanda is sparking fear among migrants who have come to France in the hope of crossing the Channel to England.

Incredulity and trepidation spread in a makeshift camp at Loon-Plage, a town near Dunkirk on the northern French coast, where migrants were waiting for a chance to cross the water.

Many said they realized that even if they reached their destination, they could quickly find themselves bundled onto a flight to Africa.
