Nicaragua using 'shoot to kill' strategy on protesters, Amnesty International says

Anti-government demonstrators protest Saturday in Managua.

(CNN)Nicaragua has instituted a "shoot to kill" policy in dealing with protests that has resulted in an "alarming number of deaths," according to an investigation by Amnesty International.

According to the 34-page report, released Tuesday, the government has violated citizens' human rights and not only used "excessive force in the context of the protests, but possibly carried out extrajudicial executions in conjunction with pro-government armed groups."
Civil unrest has entered its sixth week in Nicaragua as protests continue throughout the country. At least 76 people have been killed, according to the Inter-American Commission on Human Rights, with close to 900 injured in what appears to be the largest protests the country has seen since the civil war ended in 1990.
    Human rights lawyer and Amnesty International Director of Americas Erika Guevara-Rosas said the death toll is now at least 83.
      The Nicaraguan government has reported 15 dead since the conflict began on April 18 over social security reforms that would increase contributions by workers and employers and reduce retired workers' pensions. The reforms were subsequently reversed by the government, but the unrest has continued.
      Protesters are calling for the removal of President Daniel Ortega and "democratization" through reforms in the electoral laws, such as advancing the elections. They also demand justice for the fallen victims, calling for an investigation into the violence.

      Fresh clashes between students and armed groups

        Multiple social media posts on Monday showed university students clashing with armed groups at the National University of Engineering in Nicaragua, including posts from Guevara-Rosas and Nicaraguan human rights activist Bianca Jagger.
        According to a witness statement sent to CNN by one of her associates, Jagger saw the conflict from across the street, witnessing armed groups attacking, followed by anti-riot police "shooting live ammunition with AK-47 assault rifles."
        "They were dressed to look as if they were going to war, except that their targets were young unarmed students," Jagger said. "It was a terrifying scene."
        Guevara-Rosas said there was a second attack where she also witnessed anti-riot police with heavy weapons beating students and taking them away in pickup trucks.
        At Hospital Bautista Nicaragua on Monday night, a person on the phone said there were many injuries but said they were too busy to speak and hung up before providing a name.
        Antonia Urrejola, commissioner of the Managua-based Nicaraguan Center for Human Rights, condemned the clashes at the university, calling for an end to the violence.
        Heavy police presence was seen Monday morning by a CNN en Español crew on the ground after a radio station, Radio Ya, was set on fire. Rosario Murillo, the country's first lady and vice president, called the incident an "act of hate."
        One police officer died after being shot while working to "re-establish public order" in the area of the fire, National Police said Monday, adding that their forces were "attacked by a group of hooded men with firearms, mortars and stones."

        State accused of using armed mobs

        According to information received by Amnesty, the "Nicaraguan government has used armed individuals or pro-government armed groups that act in collusion with state officials, in particular the National Police, or with their acquiescence or tolerance."
        Known as Sandinista turbas (or mobs), these pro-government armed groups dress in attire associating them with the state, some riding on motorcycles, the report said.
        Camera footage, images and numerous interviews with family members, hospitals, human rights organizations and others reviewed by Amnesty show these gro
