CORFU, Greece—Fire service rescuers expanded a search Monday inside a burning ferry anchored off the Greek island of Corfu where 10 people remain missing. The fire on the Italian-flagged Euroferry Olympia is burning for a fourth day but rescuers have gained more expanded access inside the 183-meter (600 foot) vessel after containing the blaze. The body of a Greek man was discovered inside the ship Sunday. A total of 281 people were rescued. They included two men who were airlifted by rescuers off the ferry and a third man who managed to free himself and reach the deck of the vessel after being trapped for more than two days.
