CORINTH, Greece (AP) _ A bus slammed into the back of a water tanker truck on a country road Saturday, killing five French tourists and injuring 29, police said.

The accident occurred at about 10:00 a.m. when the Greek tour bus, carrying 47 French tourists to the ancient ruins and theater of Epidauros, hit the back end of the truck, flipped over and crashed into an orange grove, police said.

''The bus was directly behind the truck. The truck took a left turn and the bus hit it from behind, flipped over two or three times and crashed into the orange trees,'' said a police official speaking on condition of anonymity.

The official said two men, a woman and a young girl were killed instantly. A woman died after being taken to the Athens KAT hospital. Seven of the seriously injured were also transported to the hospital, he said. The other 22 injured were being treated at Corinth General Hospital.

The spokesman said the accident occurred near the seaside village of Loutra Oraias Elenis, 27 miles south of Corinth.

He said the French tourists had left Athens early Saturday for the 114-mile trip to Epidauros.

The cause of the accident was not immediately known.

Officials identified the dead as Claude Patte, 44, Michel Patrick, 40, Anne Eugenie Jouan, 9, and Marie Gabion, no age available. Another woman killed in the collision was identified only by the surname Dorre.

Police said all the tourists were from Paris.
