A jaguar has been shot dead shortly after it was used in an Olympic torch relay at a zoo in the Brazilian city of Manaus, the army said, the BBC reports.
The female jaguar escaped its handlers after the ceremony on Monday and attacked a soldier, a spokesman said.
Four tranquiliser darts failed to stop it and a soldier shot it with a pistol.
Organisers for the Rio Games said it had been a mistake to exhibit the Olympic torch next to a chained wild animal.
Animal rights groups have condemned the killing, with some questioning why the animal was involved in the Olympic event.
