At least 31 migrants bound for Britain died when their boat sank in the English Channel, in what France’s interior minister called the biggest tragedy involving migrants on the dangerous crossing to date. Interior Minister Gerald Darmanin said 34 people were believed to have been on the boat. Authorities Wednesday found 31 bodies - including those of five women and a young girl - and two survivors, he said. One person appeared to still be missing. The nationalities of the travellers were not immediately known.

Ever-increasing numbers of people fleeing conflict or poverty are risking the perilous journey in small, unseaworthy craft from France, hoping to get asylum or better opportunities in Britain. A joint French-British search operation for survivors was still under way late Wednesday. Four suspected traffickers were arrested Wednesday on suspicion of being linked to the sunken boat, Darmanin told reporters in the French port city of Calais. He said two of the suspects later appeared in court. “It’s a day of great mourning for France, for Europe, for humanity to see these people die at sea,” Darmanin said.
