At least seven people are dead after fights broke out at a maximum security prison in SC, according to authorities.
The fights started around 7:15 p.m.in three housing units at Lee Correctional Institution, which houses some of the state's most violent and longest-serving offenders.
The South Carolina Department of Corrections first posted about the "ongoing situation" late Sunday night.
The prison in Bishopville, S.C., about 60 miles northeast of Columbia, houses about 1,600 male inmates.
Lee County Fire/Rescue said ambulances from multiple jurisdictions lined up outside to tend to the wounded.
The South Carolina Law Enforcement Division and the Lee County Sheriff's Office are also responding.
Another inmate was killed during a fight at the facility in February, with two officers stabbed during a fight that broke out in Lee Correctional in 2015.
Officials have not released the names of the seven inmates killed in the riot, not have officials commented on the condition of the 17 injured inmates.
