Corrections officials have halted all outside visits to New York state prisons in the face of a growing jail guard strike and sporadic inmate unrest — as riots erupted at another upstate prison early Thursday morning.

Corrections officers at DOCCS facilities across New York state are on strike. The National Guard has been activated and deployed to a number of prisons.

As NY state prison guards are on strike​, all visitations are canceled at facilities statewide, the Department of Corrections says.
