An angry elephant kills a buffalo

Information from licensor: "When a female elephant and 3 baby elephants passed by a buffalo, the buffalo aggressively attacked the much larger female. The nose rolled up the buffalo weighing more than 500 kilograms and threw it into the air. The buffalo was seriously injured and died.
The buffalo was dozing under the tree at the time, and it was puzzling that it took the initiative to attack the elephant. Some reserve staff believe that it may be because of physical discomfort. "
