What's confusing about it? It s quite straightforward.

"Our source, the treating doctor told our reporters about two cases. One was an older child," the ABC said in a statement.

"The doctor stands by her statement that this child was allegedly raped on Nauru.

"She also told our reporters about another of her patients, a five-year-old who was allegedly sexually assaulted on Nauru.

"Our story incorrectly used quotes about the older child in referring to the younger child.

"In addition on at least one occasion the incident was referred to as a rape instead of an alleged rape. ABC News apologises for the errors and confusion."
