Multiple people were killed in a Jacksonville shooting, officials said. 

Mayor Donna Deegan, who was on the scene, confirmed that there were “a number of fatalities” following a shooting at a store, News4Jax reported. 

Deegan told the outlet a man was barricaded in the Dollar General on Kings Road. 

“This is unacceptable,” Deegan said. “One shooting is too much but these mass shootings are really hard to take.”

This is a developing story.
