All prison guards and administrative employees held hostage by inmates at correctional facilities across Ecuador have now been freed, the national prisons agency said Saturday night.

The prisons agency, SNAI, did not specify how many people had been freed but said they were undergoing medical evaluations and it would investigate those responsible for their capture. Earlier on Saturday it had said 133 guards and three administrative employees were still being held after at least 41 were released.

Ecuadorian President Daniel Noboa welcomed the news and congratulated SNAI, the armed forces and the national police for securing their release.
