A jaguar was shot and killed on Monday following the Olympic torch-lighting ceremony after it escaped its handlers and charged at an officer, the Amazon Military Command (CMA) said in a statement.
The female jaguar escaped inside of the Zoo's Center of Jungle War Instruction in São Jorge, Manaus and was shot with a tranquilizer after she escaped, said the CMA.
"The animal, even hit, went in the direction of a military that was in place," said the military. "As security procedure to protect the physical integrity of the military and team treaters, the animal was shot with a pistol and died."
The Brazilian Army has several jaguars in captivity, which have been listed as endangered by the country's environmental protection agency since 2003.
The felines are often rescued from hunters or captivity by Brazilian residents and given to the military.
The military frequently uses the jaguars, the national animal, during its parades, a practice that is condemned by specialists.
João Paulo Castro, a biologist in Brazil, told the Brazilian news site G1 that the jaguar may have fled the event out of stress.
Castro said it is not healthy to have jaguars in "such a situation” with a lot of people and a lot of noise.
People called the military's actions shameful.
"The jaguar had nothing to do with this mess, he tried to escape and ended up dead. #shame # olimpiadas2016"
Some people have questioned the role of using a live jaguar during the ceremony at all.
"What is the reason for bringing a jaguar to a carrying torch ceremony?" read the tweet in English.
