THREE RIVERS, Texas (AP) _ Authorities say several inmates have been injured in a prison riot in south Texas.

Dispatchers with the Live Oak County Sheriff's Office say multiple inmates were hurt in the riot Friday morning.

Federal Bureau of Prisons spokeswoman Traci Billings says no personnel were hurt and guards brought the riot under control quickly.

San Antonio emergency responders are assisting authorities in the small rural county. The medium-security prison about 80 miles south of San Antonio has roughly 1,200 inmates.

The riot is the second in Texas in recent weeks. A riot involving 80 inmates at the federal facility in downtown Houston broke out earlier this month.
