Prominent Azerbaijani human rights activist Leyla Yunus has been charged with several crimes, among them treason, tax evasion, and illegal entrepreneurship.
Yunus was forcibly brought to the Prosecutor-General's Office on July 30 and then charged with the crimes.
A Baku court ordered Yunus to be held in pretrial detention for three months while prosecutors prepare a case against her.
In April, Azerbaijani authorities prevented Leyla Yunus and her husband, Arif, from leaving the country, saying Leyla Yunus had been summoned as a witness in a probe against journalist Rauf Mirqadirov, who had been arrested for allegedly spying for Armenia.
The Prosecutor-General's Office said Leyla Yunus was not cooperating with investigators in the probe against Mirqadirov.
Yunus has been actively involved for years in people-to-people diplomacy with Armenian rights activists.
