All remaining 136 prison guards and administrative workers who were seized as hostages during prison riots in Ecuador were freed on Saturday night, prison authorities said. Neary 180 prison guards and civil servants had been taken hostage by rioting inmates after President Daniel Noboa launched a military crackdown on criminal groups this week, sparking a deadly confrontation with narco gangs in the South American country. Images broadcast by the police showed the guards, many in tears, exhausted and supported by their colleagues shortly after their release.
