At least 33 inmates are dead following a prison riot in northern Brazil on Friday, officials said, the second prison riot in less than a week in the country.

The latest riot at Monte Cristo Prison, in the state of Roraima, is said to have involved two rival gangs.

Experts had predicted further violence in Brazil's gang-controlled prison system after the massacre on Monday, during which members of a drug gang attacked inmates from a rival group.

Special forces were deployed after violent clashes broke out overnight, the prison governor said.

It's also becoming a flashpoint for the government of President Michel Temer, whose administration is already struggling with an economic crisis and mounting corruption allegations. "It was barbaric. Some were beheaded; others had their hearts or intestines ripped out". Moraes said he hopes to reduce that number to 18% under the new plan. Moraes offered no deadlines for the initiatives but said they would "be realistic" given the recession in Latin America's largest economy.

"Every year 500 inmates die in Brazilian prisons", former security secretary Jose Vicente da Silva told the Associated Press. There were 1,475 prisoners at the Monte Cristo prison nearly double its capacity of 750 and 15 officers at the time of the incident, Jornal O Globo reported. As of Thursday afternoon, only 65 had been recaptured.

"The federal government needs to prepare for a worst-case scenario, and that means accelerating measures to keep the situation from getting worse", said Col. Jose Vicente, a former national security adviser and risk consultant.

The riot started at around 2:30 AM on Friday at the overcrowded Monte Cristo Agricultural Penitentiary in Boa Vista.

The North Family is allied with the Rio de Janeiro-based Red Command drug gang. "This is all over Brazil".
