Two lions have been killed in Chile after they severely mauled a man who stripped naked and entered their enclosure.

The man was taken to a nearby hospital for treatment and was said to be in a grave condition.
Director Alejandra Montalba of Santiago's Metropolitan Zoo told local media the park was crowded with visitors at the time of the attack.

The 20-year-old man broke into the enclosure, took off his clothes and jumped into the middle, horrifying other visitors who witnessed the attack.

Zookeepers killed the two lions in order to save his life.
