The violence broke out between national guard troops and armed inmates at Uribana prison in the city of Barquisimeto. Officials said inmates attacked guards who were trying to carry out an inspection. Nearly all of the injuries were from gunshots.
The government sent troops to the prison after reports of clashes between inmates over the past couple days.
The prison has since been evacuated and all of the inmates were taken to other facilities. The violence was the latest in a series of bloody riots in the country's prisons.
