OUISVILLE, Ky. -- Two people were killed and four were hospitalized in shootings at a riverfront park in Louisville, police said Thursday.

Louisville Metro Police Department spokesman Dwight Mitchell said officers responded to a call of multiple shootings about 1:30 p.m. at Shawnee Park. The injuries among those taken to University Hospital were not considered life threatening, he said.

“Most people were here having a good time,” Mitchell said. “But unfortunately this tragic situation has happened.”

Mitchell had no information about any suspects or motives.

Facebook video posted by one of the event-goers, at least 20 shots are heard ringing out, CBS affiliate WLKY reports.

The video, which has over 1,000 views on Facebook, began with the man grilling with friends in the park. Shortly after the video began, gunshots could be heard.

The shootings occurred near the site of the annual Juice Bowl series of football games, which was attended by Louisville Mayor Greg Fischer.

“To have people with guns so disrespect life, Shawnee Park, and neighborhood tradition is sad and has no place in our city,” Fischer said in a Twitter post.

“My thoughts and prayers are with the families of all those impacted by today’s violence,” he said.

Youth games had just ended and two women’s teams were in the middle of a flag football game when the shots were fired. Men’s games scheduled to take place afterward were canceled.

Charlotte Waddell, a cousin of the late Muhammad Ali who has attended the football event for decades, told The Courier-Journal that she had just finished talking to the mayor when she heard several gunshots.

“This is the worst Thanksgiving ever; I’ll never be back,” she said. “I’m pretty shaken up
