Prison officials in Virginia say five guards have been injured in an attack by inmates who are MS-13 gang members. The Virginia Department of Corrections says three of the guards were stabbed and two others were transported for medical treatment Friday after being assaulted at Wallens Ridge State Prison. The agency said in a press release that six inmates involved had all been convicted of violent crimes, and that five of them were “confirmed MS-13 gang members from El Salvador, who were in this country illegally.” Officials said the sixth inmate was a U.S. citizen.
