The attack took place at around 9:45 a.m. Friday and involved six inmates, of which five were MS-13 members from El Salvador who had entered the United States illegally, the VDOC said. They had been convicted of a range of crimes including first and second degree murder, aggravated murder and rape.

Three corrections officers were stabbed by inmates in a "premeditated" attack Friday at Wallens Ridge State Prison, the Virginia Department of Corrections said.
