According to the report, the country's authorities have used spy programs that provide "extensive surveillance capabilities when installed".
The report contains, among other things, testimony from a journalist and an activist who accuse the authorities of secretly installing spy programs on their devices while they were detained.
Youth activist Nikola Ristic, who participated in the report, tells AFP that his phone was hacked by the authorities when he was arrested at a protest in November. According to him, the phone was seized by the intelligence service.
Their behavior and conversation with me was like a charade, a cover for something else, he says.
"Our investigation reveals how Serbian authorities have used surveillance technology and digital repression tactics as tools for broader state control and oppression directed at civil society", says Dinushika Dissanayake at Amnesty in a statement.
Serbia's intelligence service BIA dismisses the allegations in the report and calls them "absurd". According to a statement, the intelligence service "acts strictly in accordance with the laws of the Republic of Serbia".
