A zoo in South Korea's capital says an animal keeper has died after apparently being attacked by two lions.

Seoul Children's Grand Park official Jisun Lee said a colleague found the man unconscious and bleeding heavily from his neck and legs in the animals' enclosure, as a male and female lion wandered near him. Lee said the 52-year-old man was pronounced dead at a hospital about two hours later.

Lee said there were no witnesses or visitors at the time because the zoo has been closed since last week to prevent the spread of avian flu.

She said the zoo is waiting for police to examine security camera video and other evidence before deciding what to do with the lions.
