A bloody riot in Guatemala claimed the lives of more than six inmates after some of the prisoners fired their AK-47 assault rifles on Sunday.
Shortly after the incident, the Guatemalan Army arrived at the prison which located about 65 km (40 miles) south of Guatemala's capital city and took control of it, a spokesperson from the prison said.
According to a study published by Washington based foundation, Insight Crime, in August 2014, Guatemalan prisons were running 280 percent over capacity.
The situation is leading to an increase in criminality and pushing inmates to revolt against the poor conditions.
The Guatemala's penitentiary system is among the ten most overcrowded in the world. In 2014, 17,942 prisoners were living in the country's 6,412 prison spaces, according to the report.
In January 2014, Former Guatemalan President Perez Molina vowed to fight with growing violence in the country, promising to make 2015 the year of non-violence.
