The newspaper has reviewed over one-hundred prosecution cases in Turkey, where evidence is based on recorded telephone conversations.
"Recently, 19 women from different trade unions were arrested after they discussed on the phone how they would celebrate March 8, International Women's Day," says reporter Esref Okumus, to Swedish Radio.
The recorded conversations took place on operator Turkcell's network. TeliaSonera is the biggest co-owner of Turkcell.
Following revelations earlier this year that TeliaSonera enabled several autocratic governments to monitor their citizens, Swedish Financial Markets Minister Peter Norman demanded that state-owned companies write clearer ethical guidelines.
