An American tourist was killed by a lion at a park near Johannesburg, South Africa

An American tourist inside a car was killed and a tour operator was injured in an attack by a lion at a park near Johannesburg, South Africa, a spokesman for The Lion Park told ABC News.

The woman, who was in the passenger seat of a car and has not been identified, died while emergency services were treating her, Simpson said, adding that the driver of the car, a tour operator, sustained injuries on his arm from fighting off the lion.

Witnesses quoted in South African media said they saw two people traveling in a car with their windows open. The lion is reported to have jumped at the woman through the open window and killed her.

A State Department official confirmed an American was killed at the park but declined further comment
