A gunman opened fire inside a Walmart in Ohio and wounded four people.

Alisha Ring was shopping for Thanksgiving at Walmart in Beavercreek, Dayton when the gunman walked right past her and started shooting.

In a video posted on Facebook, Alisha said: "I was just shopping for Thanksgiving stuff and this guy walked right past me with an assault rifle and he started shooting.

"I don't know if he shot people or if people are dead or what is going on but I ran. I ran.

"He shot like ten times and I don't even know how much more afterward. I am so lucky to be alive."

The shooter died from a self-inflicted wound.
