THESSALONIKI, Greece (AP) — Authorities in Greece say that a Bulgarian woman has been killed and her husband hospitalized after diving to a great depth off Greece's northern coast. Greece's coast guard reported her death Sunday, and said her husband was transferred by helicopter to a hospital in Thessaloniki which has a unit to treat divers' decompression sickness. A staff doctor told The Associated Press on condition of anonymity that the 47-year-old man who survived said that he felt sick at a depth of about 230 meters (750 feet). His 45-year-old wife, who was with him, became unresponsive and was pulled to the surface from 60 meters (200 feet) down.
