An American woman has been killed at a lion park in Johannesburg, according to reports in South Africa.
The US Embassy says it has received reports of an "incident" involving an American citizen at the private park.
The embassy said in a statement that it has no information, but will follow up to "provide any assistance possible".
EWN, a South African news outlet, cites park officials as saying a tourist died in a lion attack.
The Lion Park is a popular destination for tourists who can drive in their own vehicles through large enclosures where lions roam freely. Visitors can also pet lion cubs in smaller pens.
