France: Neighbors could do more on trafficking

Speaking after 27 migrants died when their dinghy deflated as they made a perilous crossing of the English Channel, Darmanin said again on RTL radio that those migrants were "often attracted" by Britain's labor market.

The number of migrants attempting to cross the Channel, one of the world's busiest shipping lanes, has jumped in recent months after the British and French governments clamped down on other forms of illegal entry, such as hiding in the backs of trucks crossing from ports in France.

Darmanin accused London of "bad immigration management."

In Calais, the head of a rescuers association said they had long been warning authorities of the high possibility of such a sea tragedy.
