CNN cited the coroner in Florence County, inland from the coastal resort of Myrtle Beach, as saying one officer had died from his wounds in the incident on Wednesday.
It said the officer was among seven -- two city officers and three Florence County Sheriff's deputies, who were wounded.
There were no immediate details on the condition of the other officers, after the latest shooting involving police in the United States.
The Florence County Emergency Management office had reported on Twitter at about 5:00 pm that an "active shooter" situation was under way in Florence.
My thoughts and prayers are with the Florence County Sheriff’s Office and the Florence Police Department tonight, in South Carolina. We are forever grateful for what our Law Enforcement Officers do 24/7/365. https://t.co/ZwDmDthItD
