At least 144 refugees and migrants have been reported dead or missing after a series of maritime incidents off the coast of Mauritania, in the latest tragedy on the increasingly dangerous Atlantic migration route from West Africa to Europe's Atlantic islands.
The UN refugee agency (UNHCR) said three rescue operations were carried out from the Mauritanian port city of Nouadhibou between 14 and 18 July, bringing 387 people of various nationalities safely ashore.
