The first diver on the scene of the Chios boat tragedy in which at least 15 migrants died has told CGTN’s Evangelo Sipsas what he saw when he reached the vessel. ⁣ ⁣ The collision occurred after a migrant boat sailing towards Chios with its navigation lights switched off ignored signals from a coast guard patrol vessel and changed course, the coast guard said in a statement.⁣ ⁣ #greece #chios #migrants
