Hundreds of prisoners controlled most of a southern Colombian jail on Tuesday after a riot in which guards killed at least five inmates and injured 16 others.
Inmates seized control of their cellblocks Monday at the San Isidro district prison, which holds 1,125 prisoners.
There have been nearly 30 prison uprisings in Colombia this year. Most of the mutinies have been to protest overcrowding, unsanitary conditions, poor nutrition and medical treatment.
Colombia’s prisons were built for 28,000 inmates but hold 40,000.
