Violence took place in the same jail recently, which the authorities termed as the worst bloodshed in any prison.
A police report obtained by The Associated Press (AP) said that 10 inmates were also injured and guns were confiscated in the clashes at a prison in the coastal city of Guayaquil.
Earlier, at least 118 people were killed and 79 injured in clashes between two gangs at Littoral Jail in late September.
