Sixty-five people were rescued, but authorities were unable to revive a baby found unconscious. At least 52 migrants have died trying to cross the channel this year, authorities say, marking a six-year high.

A baby drowned when a boat carrying migrants capsized in the English Channel off the coast of France, French coast guard authorities said Friday morning.

Sixty-five people were rescued.

The accident took place off the coast of Wissant in the Pas-de-Calais region on Thursday evening.

A French navy patrol boat and a helicopter were used in the rescue and recovery operation. Authorities also said search is ongoing to find people who are still potentially missing.
