NBC新闻:9岁女孩遭野牛突然攻击

What started as a family's awe inspiring encounter turned to horror in a matter of second. A crowd of curious tours getting a close look at a massive bull bison. Then suddenly it charges, ploughing into a nine-year-old girl launching her several feet into the air. The shocking video, taken close to yellowstone's famous old faithful geyser, were wild bison graze in clusters. Bison can be aggressive, they can move quickly and they can get bothered in a moment's notice. The girl rushed to a nearby clinic. Rangers say the child is lucky, she was not seriously injured. 

Although bison attacks in yellowstone are rare, it's not the first time tours have gotten too close. Rangers say stay at least 75 feet away from animals like bison or moose and more than 300 feet from bears or wolves. They're wild animals and they're huge, they can kill you. According to park officials 50 people were standing just feet from the bison before it started charging. Getting close to wildlife is not a smart idea. And I know everybody likes to get that selfie they'd like to get that great photo but safety needs to come first. Park officials have so far decided not to issue citations to the girl's family and as of now the incident remains under investigation.
