Will the call for the PKK to disarm end in a new era of peace for the Kurds, or is this just another turn in a tortured history? In February, Abdullah Ocalan, the imprisoned leader of the Kurdistan Workers Party, known as the PKK, released a jaw-dropping written message to his followers from his jail cell, calling for the group to lay down arms and disband. In this series we explore the Kurdish issue - the persecution, the resistance and their attempts to form a state. We ask what the future holds for one of the largest stateless ethnic groups in the world scattered across Turkey, Syria, Iraq and Iran.
