Spain's maritime rescue service says it has recovered the bodies of three migrants but feared that another 17 were missing in the Mediterranean Sea.

The service says that its rescue craft found the bodies in water near a sinking boat it intercepted east of the Strait of Gibraltar. Rescuers saved 36 men of sub-Saharan origins from the boat and said the rescued migrants told them another 17 men who had traveled with them were missing.

In total, Spain's maritime service pulled 509 migrants from 15 small boats on Friday.

The United Nations says that 337 of the 1,783 migrants who have died trying to reach Europe by sea in 2018 have perished in waters near Spain.

11:15 a.m.

Greek police say they have recovered the bodies of 11 people believed to be migrants who recently crossed from Turkey, after the car they were travelling in crashed in northern Greece.

Police said the crash occurred just after 5 a.m. (0200 GMT) Saturday near the town of Kavala. The car, which had been heading to the main northern city of Thessaloniki, collided with a truck heading in the opposite direction and burst into flames.

All those in the car were killed. The truck driver was being treated for injuries in a hospital in northern Greece.

Greek authorities have been seeing an increase in people illegally crossing the Greek-Turkish border in recent months. Many are transported to Thessaloniki, where they head to police stations to be registered and apply for asylum.
