Ecuador’s president has declared a state of emergency in the prison system following a battle among gang members in a coastal lockup that killed at least 116 people and injured 80 in what authorities say was the worst prison bloodbath ever in the country. Officials said at least five of the dead were found to have been beheaded.

President Guillermo Lasso decreed a state of emergency Wednesday, which will give the government powers that include deploying police and soldiers inside prisons. The order came a day after bloodshed at the Litoral penitentiary in Guayaquil that officials blamed on gangs linked to international drug cartels fighting for control of the facility.
