MANAGUA, Nicaragua (AP) — A Nicaraguan rights group says authorities will file charges against a group of government opponents, including 13 who were arrested for supporting protesters demanding freedom for people they consider political prisoners.

María Oviedo is a lawyer with the Permanent Commission on Human Rights in Nicaragua. She said Sunday that charges will be formally presented Monday. There was no immediate word on what crime or crimes may be charged, or what sort of punishment the activists could face.

The 13 were detained Thursday when they tried to enter Masaya’s San Miguel church to deliver water to the hunger strikers.

Police have maintained a tight cordon around the area, and water and electricity services have been cut.

President Daniel Ortega’s government has repeatedly accused opposition protesters of being coup plotters and terrorists.
