Iranian authorities have arrested three female human rights lawyers on for so-called security related offenses. Maryam Kianersi, Maryam Karbasi, and Sara Sabaghian were taken into custody after they arrived on a flight from Turkey. Sara Sabaghian reportedly represented Hossein Ronaghi in court after his arrest for blog posts which criticized the Iranian government. Ronaghi is currently appealing a 15-year jail sentence for his alleged crime. All three women had previously signed an open letter advocating for the release of Nasrin Sotoudeh, a well-known human rights lawyer imprisoned in Evin Prison. Kianersi was on the defense team of Kobra Najjar, a woman sentenced to death by stoning who was acquitted and freed about two years ago.
