A Turkish court sentenced four Amnesty International activists to between two and six years in prison on terrorism charges in a high-profile trial Friday, which the human rights group described as a "travesty of justice of spectacular proportions."

The honorary chair of Amnesty International Turkey, Taner Kilic, was sentenced to six years and three months in jail for being a member of terror organization, while the group's former director İdil Eser was sentenced to two years and one month for aiding a terror organization. Amnesty members Günal Kursun and Özlem Dalgiran were also given two years and one month sentences for aiding a terror group. The human rights group denies all the charges and said that every allegation against its members has been "comprehensively exposed as a baseless slur."

Another seven defendants were acquitted. The 11 human rights activists were arrested and charged in the summer of 2017 on terrorism charges.

The defendants have the right to appeal to the Court of Appeal, which Amnesty Turkey tweeted that they will use. "As we said before the trial, we will not accept even one of our friends to be sentenced. We will continue to follow the case through higher courts," it said. The four activists will not be imprisoned pending their appeals. The appeal process could take months or years.
